Naveen Mamindlapalli says: ==================== Add tc hardware offloads This patch series adds support for tc hardware offloads. Patch #1 adds support for offloading flows that matches IP tos and IP protocol which will be used by tc hw offload support. Also added ethtool n-tuple filter to code to offload the flows matching the above fields. Patch #2 adds tc flower hardware offload support on ingress traffic. Patch #3 adds TC flower offload stats. Patch #4 adds tc TC_MATCHALL egress ratelimiting offload. * tc flower hardware offload in PF driver The driver parses the flow match fields and actions received from the tc subsystem and adds/delete MCAM rules for the same. Each flow contains set of match and action fields. If the action or fields are not supported, the rule cannot be offloaded to hardware. The tc uses same set of MCAM rules allocated for ethtool n-tuple filters. So, at a time only one entity can offload the flows to hardware, they're made mutually exclusive in the driver. Following match and actions are supported. Match: Eth dst_mac, EtherType, 802.1Q {vlan_id,vlan_prio}, vlan EtherType, IP proto {tcp,udp,sctp,icmp,icmp6}, IPv4 tos, IPv4{dst_ip,src_ip}, L4 proto {dst_port|src_port number}. Actions: drop, accept, vlan pop, redirect to another port on the device. The Hardware stats are also supported. Currently only packet counter stats are updated. * tc egress rate limiting support Added TC-MATCHALL classifier offload with police action applied for all egress traffic on the specified interface. ==================== Signed-off-by:David S.

Add TC_MATCHALL egress ratelimiting offload support with POLICE action for entire traffic going out of the interface. Eg: To ratelimit egress traffic to 100Mbps $ ethtool -K eth0 hw-tc-offload on $ tc qdisc add dev eth0 clsact $ tc filter add dev eth0 egress matchall skip_sw \ action police rate 100Mbit burst 16Kbit HW supports a max burst size of ~128KB. Only one ratelimiting filter can be installed at a time. Signed-off-by:Sunil Goutham <sgoutham@marvell.com> Signed-off-by:

This patch adds support for tc flower hardware offload on ingress traffic. Since the tc-flower filter rules use the same set of MCAM rules as the n-tuple filters, the n-tuple filters and tc flower rules are mutually exclusive. When one of the feature is enabled using ethtool, the other feature is disabled in the driver. By default the driver enables n-tuple filters during initialization. The following flow keys are supported. -> Ethernet: dst_mac -> L2 proto: all protocols -> VLAN (802.1q): vlan_id/vlan_prio -> IPv4: dst_ip/src_ip/ip_proto{tcp|udp|sctp|icmp}/ip_tos -> IPv6: ip_proto{icmpv6} -> L4(tcp/udp/sctp): dst_port/src_port The following flow actions are supported. -> drop -> accept -> redirect -> vlan pop The flow action supports multiple actions when vlan pop is specified as the first action. The redirect action supports redirecting to the PF/VF of same PCI device. Redirecting to other PCI NIX devices is not supported. Example #1: Add a tc filter rule to drop UDP traffic with dest port 80 # ethtool -K eth0 hw-tc-offload on # tc qdisc add dev eth0 ingress # tc filter add dev eth0 protocol ip parent ffff: flower ip_proto \ udp dst_port 80 action drop Example #2: Add a tc filter rule to redirect ingress traffic on eth0 with vlan id 3 to eth6 (ex: eth0 vf0) after stripping the vlan hdr. # ethtool -K eth0 hw-tc-offload on # tc qdisc add dev eth0 ingress # tc filter add dev eth0 parent ffff: protocol 802.1Q flower \ vlan_id 3 vlan_ethtype ipv4 action vlan pop action mirred \ ingress redirect dev eth6 Example #3: List the ingress filter rules # tc -s filter show dev eth4 ingress Example #4: Delete tc flower filter rule with handle 0x1 # tc filter del dev eth0 ingress protocol ip pref 49152 \ handle 1 flower Signed-off-by: -

Add support for programming the HW MCAM match key with IP tos, IP(v6) proto icmp/icmpv6, allowing flow offload rules to be installed using those fields. The NPC HW extracts layer type, which will be used as a matching criteria for different IP protocols. The ethtool n-tuple filter logic has been updated to parse the IP tos and l4proto for HW offloading. l4proto tcp/udp/sctp/ah/esp/icmp are supported. See example usage below. Ex: Redirect l4proto icmp to vf 0 queue 0 ethtool -U eth0 flow-type ip4 l4proto 1 action vf 0 queue 0 Ex: Redirect flow with ip tos 8 to vf 0 queue 0 ethtool -U eth0 flow-type ip4 tos 8 vf 0 queue 0 Signed-off-by:

On some platforms, e.g., the ZynqMP, devm_clk_get can return -EPROBE_DEFER if the clock controller, which is implemented in firmware, has not been probed yet. As clk_init is only called during probe, use dev_err_probe to simplify the error message and hide it for -EPROBE_DEFER. Signed-off-by:

Marek Behún says: ==================== Add support for mv88e6393x family of Marvell after 2 months I finally had time to send v17 of Amethyst patches. This series is tested on Marvell CN9130-CRB. Changes since v16: - dropped patches adding 5gbase-r, since they are already merged - rebased onto net-next/master - driver API renamed set_egress_flood() method into 2 methods for ucast/mcast floods, so this is fixed Changes from v15: - put 10000baseKR_Full back into phylink_validate method for Amethyst, it seems I misunderstood the meaning behind things and removed it from v15 - removed erratum 3.7, since the procedure is done anyway in mv88e6390_serdes_pcs_config - renumbered errata 3.6 and 3.8 to 4.6 and 4.8, according to newer version of the errata document - refactored errata code a little and removed duplicate macro definitions (for example MV88E6390_SGMII_CONTROL is already called MV88E6390_SGMII_BMCR) Changes from v14: - added my Signed-off-by tags to Pavana's patches, since I am sending them (as suggested by Andrew) - added documentation to second patch adding 5gbase-r mode (as requested by Russell) - added Reviewed-by tags - applied Vladimir's suggestions: - reduced indentation level in mv88e6xxx_set_egress_port and mv88e6393x_serdes_port_config - removed 10000baseKR_Full from mv88e6393x_phylink_validate - removed PHY_INTERFACE_MODE_10GKR from mv88e6xxx_port_set_cmode Changes from v13: - added patch that wraps .set_egress_port into mv88e6xxx_set_egress_port, so that we do not have to set chip->*gress_dest_port members in every implementation of this method - for the patch that adds Amethyst support: - added more information into commit message - added these methods for mv88e6393x_ops: .port_sync_link .port_setup_message_port .port_max_speed_mode (new implementation needed) .atu_get_hash .atu_set_hash .serdes_pcs_config .serdes_pcs_an_restart .serdes_pcs_link_up - this device can set upstream port per port, so implement .port_set_upstream_port instead of .set_cpu_port - removed USXGMII cmode (not yet supported, working on it) - added debug messages into mv88e6393x_port_set_speed_duplex - added Amethyst errata 4.5 (EEE should be disabled on SERDES ports) - fixed 5gbase-r serdes configuration and interrupt handling - refactored mv88e6393x_serdes_setup_errata - refactored mv88e6393x_port_policy_write - added patch implementing .port_set_policy for Amethyst ==================== Signed-off-by: -

The 16-bit Port Policy CTL register from older chips is on 6393x changed to Port Policy MGMT CTL, which can access more data, but indirectly and via 8-bit registers. The original 16-bit value is divided into first two 8-bit register in the Port Policy MGMT CTL. We can therefore use the previous code to compute the mask and shift, and then - if 0 <= shift < 8, we access register 0 in Port Policy MGMT CTL - if 8 <= shift < 16, we access register 1 in Port Policy MGMT CTL There are in fact other possible policy settings for Amethyst which could be added here, but this can be done in the future.

The Marvell 88E6393X device is a single-chip integration of a 11-port Ethernet switch with eight integrated Gigabit Ethernet (GbE) transceivers and three 10-Gigabit interfaces. This patch adds functionalities specific to mv88e6393x family (88E6393X, 88E6193X and 88E6191X). The main differences between previous devices and this one are: - port 0 can be a SERDES port - all SERDESes are one-lane, eg. no XAUI nor RXAUI - on the other hand the SERDESes can do USXGMII, 10GBASER and 5GBASER (on 6191X only one SERDES is capable of more than 1g; USXGMII is not yet supported with this change) - Port Policy CTL register is changed to Port Policy MGMT CTL register, via which several more registers can be accessed indirectly - egress monitor port is configured differently - ingress monitor/CPU/mirror ports are configured differently and can be configured per port (ie. each port can have different ingress monitor port, for example) - port speed AltBit works differently than previously - PHY registers can be also accessed via MDIO address 0x18 and 0x19 (on previous devices they could be accessed only via Global 2 offsets 0x18 and 0x19, which means two indirections; this feature is not yet leveraged with thiis commit) Co-developed-by:

A mcam rule described by mcam_rule struct has all the info such as the hardware MCAM entry number, match criteria and corresponding action etc. All mcam rules are stored in a linked list mcam->rules. When adding/updating a rule to the mcam->rules it is checked if a rule already exists for the mcam entry. If the rule already exists, the same rule is updated instead of creating new rule. This way only one mcam_rule exists for the only one default unicast entry installed by AF. But a PF/VF can get different NIXLF (or default unicast entry number) after a attach-detach-attach sequence. When that happens mcam_rules list end up with two default unicast rules. Fix the problem by deleting the default unicast rule list node always when disabling mcam rules. Signed-off-by:

This patch adds support for multi channel NIX promisc entry. Packets sent on all those channels by the host should be received by the interface to which those channels belong. Channel count, if greater than 1, should be power of 2 as only one promisc entry is available for the interface. Key mask is modified such that incoming packets from channel base to channel count are directed to the same pci function. Signed-off-by:

mlxsw: Allow 802.1d and .1ad VxLAN bridges to coexist on Spectrum>=2 Ido Schimmel says: ==================== This patchset allows user space to simultaneously configure both 802.1d and 802.1ad VxLAN bridges on Spectrum-2 and later ASICs. 802.1ad VxLAN bridges are still forbidden on Spectrum-1. The reason for the current limitation is that up until now the EtherType that was pushed to decapsulated VxLAN packets was a property of the tunnel port, of which there is only one. This meant that a 802.1ad VxLAN bridge could not be configured if the tunnel port was already configured to push a 802.1q tag. This patchset improves the situation by making two changes. First, decapsulated packets are marked as having their EtherType decided by the egress port. Second, local ports member in the bridge (e.g., swp1) are configured to set the correct egress EtherType. Patchset overview: Patch #1 adds a register required for the first change Patches #2-#3 add the register required for the second change and a corresponding API Patch #4 prepares the driver for the split in behavior between Spectrum-1 and later ASICs Patch #5 performs the two above mentioned changes to allow the driver to support simultaneous 802.1ad and 802.1d VxLAN bridges on Spectrum-2 and later ASICs Patch #6 adds a selftest Patch #7 removes a selftest that verified the limitation that was lifted by this patchset ==================== Signed-off-by: -

Currently only one EtherType can be configured for pushing in tunnels because EtherType is configured using SPVID.et_vlan for tunnel port. This behavior is forbidden by comparing mlxsw_sp_nve_config struct for each new tunnel, the struct contains 'ethertype' field which means that only one EtherType is legal at any given time. Remove 'ethertype' field to allow creating VxLAN devices with different bridges. To allow using several types of VxLAN bridges at the same time, the EtherType should be determined at the egress port. This behavior is achieved by setting SPVID to decide which EtherType to push at egress and for each local_port which is member in 802.1ad bridge, set SPEVET.et_vlan to ether_type1 (i.e., 0x88A8). Use switchdev_ops->init() to set different mlxsw_sp_bridge_ops for different ASICs in order to be able to split the behavior when port joins / leaves an 802.1ad bridge in different ASICs.

A subsequent patch will need to implement different set of operations when a port joins / leaves an 802.1ad bridge, based on the ASIC type. Prepare for this change by allowing to initialize the bridge module based on the ASIC type via 'struct mlxsw_sp_switchdev_ops'. Signed-off-by:

A subsequent patch will cause decapsulated packets to have their EtherType determined by the egress port. Add mlxsw_sp_port_egress_ethtype_set() which will be called when a port joins an 802.1ad bridge, so that it will set an 802.1ad EtherType on decapsulated packets transmitted through it, instead of the default 802.1q EtherType.

SPEVET configures which EtherType to push at egress for packets incoming through a local port for which 'SPVID.egr_et_set' is set. The next patches will use SPEVET to configure EtherType 0x88A8 and 0x8100 for local ports member in 802.1ad and 802.1q bridges, respectively. This allows using dual VxLAN bridges (802.1d and 802.1ad at the same time). Signed-off-by:

SPVID.egr_et_set=1 means that when VLAN is pushed at ingress (for untagged packets or for QinQ push mode) then the EtherType is decided at the egress port.
