Add Spectrum-2 ASIC port type-speed operations. Since multiple ethtool link modes are represented using a single bit in the ASIC, the driver forces the user to configure all types per a specific speed. For example, if the user wants to advertise 100Gbps 4-lanes speed, he should advertise all the types of 100Gbps 4-lanes speed that are supported by the ASIC as shown below: Supported ethtool bits for 100Gbps 4-lanes: 0x1000000000 100000baseKR4 Full 0x2000000000 100000baseSR4 Full 0x4000000000 100000baseCR4 Full 0x8000000000 100000baseLR4_ER4 Full Command for advertising 100Gbps 4-lanes: ethtool -s enp3s0np1 advertise 0xF000000000 Signed-off-by:Shalom Toledo <shalomt@mellanox.com> Acked-by:

I thought header search paths to tools/include(/uapi) were unneeded, but it looks like a build error occurs depending on the compiler. Commit 303a339f ("bpfilter: remove extra header search paths for bpfilter_umh") reintroduced the build error fixed by commit ae40832e ("bpfilter: fix a build err"). Apology for the breakage, and thanks to Guenter for reporting this. Fixes: 303a339f ("bpfilter: remove extra header search paths for bpfilter_umh") Reported-by:

Vinod Koul says: ==================== net: phy: at803x: Update delays for RGMII modes Peter[1] reported that patch cd28d1d6: ("net: phy: at803x: Disable phy delay for RGMII mode") caused regression on am335x-evmsk board. This board expects the Phy delay to be enabled but specified RGMII mode which refers to delays being disabled. So fix this by disabling delay only for RGMII mode and enable for RGMII_ID and RGMII_TXID/RXID modes. While at it, as pointed by Dave, don't inline the helpers.

Per "Documentation/devicetree/bindings/net/ethernet.txt" RGMII mode should not have delay in PHY whereas RGMII_ID and RGMII_RXID/RGMII_TXID can have delay in PHY. So disable the delay only for RGMII mode and enable for other modes. Also treat the default case as disabled delays.

For tcindex filter, it is too late to initialize the net pointer in tcf_exts_validate(), as tcf_exts_get_net() requires a non-NULL net pointer. We can just move its initialization into tcf_exts_init(), which just requires an additional parameter. This makes the code in tcindex_alloc_perfect_hash() prettier.

Maxim Mikityanskiy says: ==================== AF_PACKET transport_offset fix This patch series contains the implementation of the RFC that was posted on this mailing list previously: https://www.spinics.net/lists/netdev/msg541709.html It fixes having incorrect skb->transport_header values in cases when dissect fails. Having correct values set by the kernel fixes mlx5 operation and allows to remove some unnecessary code flows in mlx5. v2 changes: - Rebase against the fresh net-next. - Don't return bool from skb_probe_transport_header (and don't rename the function). - WARN_ON_ONCE and error path in case of GSO without the L4 header. ==================== Acked-by:

c72219b7 introduced tpacket_set_protocol that parses the Ethernet L2 header and sets skb->protocol if it's unset. It is no longer needed since the introduction of packet_parse_headers. In case of SOCK_RAW and unset skb->protocol, packet_parse_headers asks the driver to tell the protocol number, and it's implemented for all Ethernet devices. As the old function supported only Ethernet, no functionality is lost. Signed-off-by:

Introduce a new optional header_ops callback called parse_protocol and a wrapper function dev_parse_header_protocol, similar to dev_parse_header. The new callback's purpose is to extract the protocol number from the L2 header, the format of which is known to the driver, but not to the upper layers of the stack. Signed-off-by:

If the socket was created with socket(AF_PACKET, SOCK_RAW, 0), skb->protocol will be unset, __skb_flow_dissect() will fail, and skb_probe_transport_header() will fall back to the offset_hint, making the resulting skb_transport_offset incorrect. If, however, there is no transport header in the packet, transport_header shouldn't be set to an arbitrary value. Fix it by leaving the transport offset unset if it couldn't be found, to be explicit rather than to fill it with some wrong value. It changes the behavior, but if some code relied on the old behavior, it would be broken anyway, as the old one is incorrect. Signed-off-by:

Florian Fainelli says: ==================== net: dsa: VLAN devices w/ filtering This patch series supports having VLAN devices on top of DSA/switch ports while the switch has VLAN filtering globally turned on (as is the case with Broadcom switches). Whether the switch does global or per-port VLAN filtering, having VLAN entries for these VLAN devices is beneficial. We take care of a few possibly problematic cases: - adding a VLAN device while there is an existing VLAN entry created by a VLAN aware bridge. The entire bridge's VLAN database and not just the specific bridge port is being checked to be safe and conserative - adding a bridge VLAN entry when there is an existing VLAN device created is also not possible because that would lead to the bridge being able to manipulate the VLAN device's VID/attributes under its feet - enslaving a VLAN device into a VLAN aware bridge since that duplicates functionality already offered by the VLAN aware bridge Here are the different test cases that were run to exercise this: ip addr flush dev gphy ip link add dev br0 type bridge echo 1 > /sys/class/net/br0/bridge/vlan_filtering ip link set dev gphy master br0 udhcpc -i br0 vconfig add rgmii_1 100 ifconfig rgmii_1.100 192.168.100.10 ping -c 2 192.168.100.1 vconfig add br0 42 bridge vlan add vid 42 dev gphy bridge vlan add vid 42 dev br0 self ifconfig br0.42 192.168.42.2 ping -c 2 192.168.42.1 ip link del rgmii_1.100 vconfig add rgmii_1 100 ifconfig rgmii_1.100 192.168.100.10 ping -c 2 192.168.100.1 echo 0 > /sys/class/net/br0/bridge/vlan_filtering ping -c 2 192.168.100.1 ip link del rgmii_1.100 echo 1 > /sys/class/net/br0/bridge/vlan_filtering vconfig add rgmii_1 100 brctl addif br0 rgmii_1 bridge vlan add vid 100 dev rgmii_1 vconfig rem rgmii_1.100 bridge vlan add vid 100 dev rgmii_1 vconfig add rgmii_1 100 bridge vlan del vid 100 dev rgmii_1 vconfig add rgmii_1 100 brctl addif br0 rgmii_1.100 ==================== Signed-off-by: -

In order to properly support VLAN filtering being enabled/disabled on a bridge, while having other ports being non bridge port members, we need to support the ndo_vlan_rx_{add,kill}_vid callbacks in order to make sure the non-bridge ports can continue receiving VLAN tags, even when the switch is globally configured to do ingress/egress VID checking. Since we can call dsa_port_vlan_{add,del} with a bridge_dev pointer NULL, we now need to check that in these two functions. We specifically deal with two possibly problematic cases: - creating a bridge VLAN entry while there is an existing VLAN device claiming that same VID - creating a VLAN device while there is an existing bridge VLAN entry with that VID Those are both resolved with returning -EBUSY back to user-space.

VLAN devices on top of a DSA network device which is already part of a bridge and with said bridge being VLAN aware should not be allowed to be enslaved into that bridge. For one, this duplicates functionality offered by the VLAN aware bridge which supports tagged and untagged VLAN frames processing and it would make things needlessly complex to e.g.: propagate FDB/MDB accordingly.
