Sometimes it can be quite opaque even for me why the driver decided to reset the switch. So instead of adding dump_stack() calls each time for debugging, just add a reset reason to sja1105_static_config_reload calls which gets printed to the console. Signed-off-by:

Matthias Schiffer says: ==================== Implement get_link_ksettings for VXLAN and bridge Mesh routing protocol batman-adv (in particular the new BATMAN_V algorithm) uses the link speed reported by get_link_ksettings to determine a path metric for wired links. In the mesh framework Gluon [1], we layer VXLAN and sometimes bridge interfaces on our Ethernet links. These patches implement get_link_ksettings for these two interface types. While this is obviously not accurate for bridges with multiple active ports, it's much better than having no estimate at all (and in the particular setup of Gluon, bridges with a single port aren't completely uncommon).

We return the maximum speed of all active ports. This matches how the link speed would give an upper limit for traffic to/from any single peer if the bridge were replaced with a hardware switch. Signed-off-by:

It is possible for a switch driver to use NET_DSA_TAG_8021Q as a valid DSA tagging protocol since it registers itself as such, unfortunately since there are not xmit or rcv functions provided, the lack of a xmit() function will lead to a NPD in dsa_slave_xmit() to start with. net/dsa/tag_8021q.c is only comprised of a set of helper functions at the moment, but is not a fully autonomous or functional tagging "driver" (though it could become later on). We do not have any users of NET_DSA_TAG_8021Q so now is a good time to make sure there are not issues being encountered by making this file strictly a place holder for helper functions. Reviewed-by:

In commit 25b0b9c4 ("tipc: handle collisions of 32-bit node address hash values"), the 32-bit node address only generated after one second trial period expired. However the self's addr in struct tipc_monitor do not update according to node address generated. This lead to it is always zero as initial value. As result, sorting algorithm using this value does not work as expected, neither neighbor monitoring framework. In this commit, we add a fix to update self's addr when 32-bit node address generated.

Pablo Neira Ayuso says: ==================== netfilter flowtable hardware offload The following patchset adds hardware offload support for the flowtable infrastructure [1]. This infrastructure provides a fast datapath for the classic Linux forwarding path that users can enable through policy, eg. table inet x { flowtable f { hook ingress priority 10 devices = { eth0, eth1 } flags offload } chain y { type filter hook forward priority 0; policy accept; ip protocol tcp flow offload @f } } This example above enables the fastpath for TCP traffic between devices eth0 and eth1. Users can turn on the hardware offload through the 'offload' flag from the flowtable definition. If this new flag is not specified, the software flowtable datapath is used. This patchset is composed of 4 preparation patches: room to extend this infrastructure, eg. accelerate bridge forwarding. And 2 patches to add the hardware offload control and data planes: hardware offload. This includes a new NFTA_FLOWTABLE_FLAGS netlink attribute to convey the optional NF_FLOWTABLE_HW_OFFLOAD flag. API available at net/core/flow_offload.h to represent the flow through two flow_rule objects to configure an exact 5-tuple matching on each direction plus the corresponding forwarding actions, that is, the MAC address, NAT and checksum updates; and port redirection in order to configure the hardware datapath. This patch only supports for IPv4 support and statistics collection for flow aging as an initial step. This patchset introduces a new flow_block callback type that needs to be set up to configure the flowtable hardware offload. The first client of this infrastructure follows up after this batch. I would like to thank Mellanox for developing the first upstream driver to use this infrastructure. [1] Documentation/networking/nf_flowtable.txt ==================== Signed-off-by: -

This patch adds the dataplane hardware offload to the flowtable infrastructure. Three new flags represent the hardware state of this flow: * FLOW_OFFLOAD_HW: This flow entry resides in the hardware. * FLOW_OFFLOAD_HW_DYING: This flow entry has been scheduled to be remove from hardware. This might be triggered by either packet path (via TCP RST/FIN packet) or via aging. * FLOW_OFFLOAD_HW_DEAD: This flow entry has been already removed from the hardware, the software garbage collector can remove it from the software flowtable. This patch supports for: * IPv4 only. * Aging via FLOW_CLS_STATS, no packet and byte counter synchronization at this stage. This patch also adds the action callback that specifies how to convert the flow entry into the flow_rule object that is passed to the driver. Signed-off-by:

The first patch is by Gustavo A. R. Silva and removes unused code in the generic CAN infrastructure. The next three patches target the mcp251x driver. The one by Andy Shevchenko removes the legacy platform data support from the driver. The other two are by Timo Schlüßler and reset the device only when needed, to prevent glitches on the output when GPIO support is added. I'm contributing two patches fixing checkpatch warnings in the c_can_platform and peak_canfd driver. Stephane Grosjean's patch for the peak_canfd driver adds hw timestamps support in rx skbs. The next three patches target the xilinx_can driver. One patch by me to fix checkpatch warnings, one patch by Anssi Hannula to avoid non requested bus error frames, and a patch by YueHaibing that switches the driver to devm_platform_ioremap_resource(). Pankaj Sharma contributes two patches for the m_can driver, the first one adds support for one shot mode, the other support for handling arbitration errors. Followed by four patches by YueHaibing, switching the grcan, ifi, rcar, and sun4i drivers to devm_platform_ioremap_resource() I'm contributing cleanup patches for the rx-offload helper, while Joakim Zhang's patch prepares the rx-offload helper for CAN-FD support. The rx offload users flexcan and ti_hecc are converted accordingly. The remaining twelve patches target the flexcan driver. First Joakim Zhang switches the driver to devm_platform_ioremap_resource(). The remaining eleven patch are by me and clean up the abstract the access of the iflag1 and iflag2 register both for RX and TX mailboxes. This is a preparation for the upcoming CAN-FD support. ==================== Signed-off-by:

The sfc driver can drop packets processed with XDP, notably when running out of buffer space on XDP_TX, or returning an unknown XDP action. This increments the rx_xdp_bad_drops ethtool counter. Call trace_xdp_exception everywhere rx_xdp_bad_drops is incremented, except for fragmented RX packets as the XDP program hasn't run yet. This allows it to easily be monitored from userspace. This mirrors the behavior of other drivers. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Add extended ACK for EMADs Shalom says: Ethernet Management Datagrams (EMADs) are Ethernet packets sent between the driver and device's firmware. They are used to pass various configurations to the device, but also to get events (e.g., port up) from it. After the Ethernet header, these packets are built in a TLV format. Up until now, whenever the driver issued an erroneous register access it only got an error code indicating a bad parameter was used. This patch set adds a new TLV (string TLV) that can be used by the firmware to encode a 128 character string describing the error. The new TLV is allocated by the driver and set to zeros. In case of error, the driver will check the length of the string in the response and report it using devlink hwerr tracepoint. Example: $ perf record -a -q -e devlink:devlink_hwerr & $ pkill -2 perf $ perf script -F trace:event,trace | grep hwerr devlink:devlink_hwerr: bus_name=pci dev_name=0000:03:00.0 driver_name=mlxsw_spectrum err=7 (tid=9913892d00001593,reg_id=8018(rauhtd)) bad parameter (inside er_rauhtd_write_query(), num_rec=32 is over the maximum number of records supported) Patch #1 parses the offsets of the different TLVs in incoming EMADs and stores them in the skb's control block. This makes it easier to later add new TLVs. Patches #2-#3 remove deprecated TLVs and add string TLV definition. Patches #4-#7 gradually add support for the new string TLV. v2: * Use existing devlink hwerr tracepoint to report the error string, instead of printing it to kernel log ==================== Signed-off-by: -
