It is not appropriate for the mlx5e_num_channels_changed function to be called solely for updating the TX queues, even if the channels number has not been changed. Move the code responsible for updating the TC and TX queues from mlx5e_num_channels_changed and produce a new function called mlx5e_update_tc_and_tx_queues. This new function should only be called when the channels number remains unchanged. Signed-off-by:

This patch adds to mlx5 drivers support for 8 ports HCAs. Starting with ConnectX-8 HCAs with 8 ports are possible. As most driver parts aren't affected by such configuration most driver code is unchanged. Specially the only affected areas are: - Lag - Multiport E-Switch - Single FDB E-Switch All of the above are already factored in generic way, and LAG and VF LAG are tested, so all that left is to change a #define and remove checks which are no longer needed. However, Multiport E-Switch is not tested yet, so it is left untouched. This patch will allow to create hardware LAG/VF LAG when all 8 ports are added to the same bond device. for example, In order to activate the hardware lag a user can execute the following: ip link add bond0 type bond ip link set bond0 type bond miimon 100 mode 2 ip link set eth2 master bond0 ip link set eth3 master bond0 ip link set eth4 master bond0 ip link set eth5 master bond0 ip link set eth6 master bond0 ip link set eth7 master bond0 ip link set eth8 master bond0 ip link set eth9 master bond0 Where eth2, eth3, eth4, eth5, eth6, eth7, eth8 and eth9 are the PFs of the same HCA.

Before DCB support, the KSZ driver had only PCP as source of packet priority values. To avoid regressions, make PCP only as default value. User will need enable DSCP support manually. This patch do not affect other KSZ8 related quirks. User will still be warned by setting not support configurations for the port 2. Signed-off-by:

IPV is added and used term in 802.1Qci PSFP and merged into 802.1Q (from 802.1Q-2018) for another functions. Even it does similar operation holding temporal priority value internally (as it is named), because KSZ datasheet doesn't use the term of IPV (Internal Priority Value) and avoiding any confusion later when PSFP is in the Linux world, it is better to rename IPV to IPM (Internal Priority Mapping). In addition, LAN937x documentation already use IPV for 802.1Qci PSFP related functionality. Suggested-by:

For type String and Binary we are currently usinig the exact-len limit value as is without attempting any name resolution. However, the spec may specify the name of a constant rather than an actual value, which would result in using the constant name as is and thus break the policy. Ensure the limit value is passed to get_limit(), which will always attempt resolving the name before printing the policy rule. Signed-off-by:

A way for an application to know if an MPTCP connection fell back to TCP is to use getsockopt(MPTCP_INFO) and look for errors. The issue with this technique is that the same errors -- EOPNOTSUPP (IPv4) and ENOPROTOOPT (IPv6) -- are returned if there was a fallback, *or* if the kernel doesn't support this socket option. The userspace then has to look at the kernel version to understand what the errors mean. It is not clean, and it doesn't take into account older kernels where the socket option has been backported. A cleaner way would be to expose this info to the TCP socket level. In case of MPTCP socket where no fallback happened, the socket options for the TCP level will be handled in MPTCP code, in mptcp_getsockopt_sol_tcp(). If not, that will be in TCP code, in do_tcp_getsockopt(). So MPTCP simply has to set the value 1, while TCP has to set 0. If the socket option is not supported, one of these two errors will be reported: - EOPNOTSUPP (95 - Operation not supported) for MPTCP sockets - ENOPROTOOPT (92 - Protocol not available) for TCP sockets, e.g. on the socket received after an 'accept()', when the client didn't request to use MPTCP: this socket will be a TCP one, even if the listen socket was an MPTCP one. With this new option, the kernel can return a clear answer to both "Is this kernel new enough to tell me the fallback status?" and "If it is new enough, is it currently a TCP or MPTCP socket?" questions, while not breaking the previous method.

{inet,ipv6}_gro_receive functions perform flush checks (ttl, flags, iph->id, ...) against all packets in a loop. These flush checks are used in all merging UDP and TCP flows. These checks need to be done only once and only against the found p skb, since they only affect flush and not same_flow. This patch leverages correct network header offsets from the cb for both outer and inner network headers - allowing these checks to be done only once, in tcp_gro_receive and udp_gro_receive_segment. As a result, NAPI_GRO_CB(p)->flush is not used at all. In addition, flush_id checks are more declarative and contained in inet_gro_flush, thus removing the need for flush_id in napi_gro_cb. This results in less parsing code for non-loop flush tests for TCP and UDP flows. To make sure results are not within noise range - I've made netfilter drop all TCP packets, and measured CPU performance in GRO (in this case GRO is responsible for about 50% of the CPU utilization). perf top while replaying 64 parallel IP/TCP streams merging in GRO: (gro_receive_network_flush is compiled inline to tcp_gro_receive) net-next: 6.94% [kernel] [k] inet_gro_receive 3.02% [kernel] [k] tcp_gro_receive patch applied: 4.27% [kernel] [k] tcp_gro_receive 4.22% [kernel] [k] inet_gro_receive perf top while replaying 64 parallel IP/IP/TCP streams merging in GRO (same results for any encapsulation, in this case inet_gro_receive is top offender in net-next) net-next: 10.09% [kernel] [k] inet_gro_receive 2.08% [kernel] [k] tcp_gro_receive patch applied: 6.97% [kernel] [k] inet_gro_receive 3.68% [kernel] [k] tcp_gro_receive Signed-off-by: -

strscpy copies as much of the string as possible, meaning that the destination string will be truncated in case of no space. As this is a non-critical error in our case, adding a debug level print for indication. This patch also removes a -1 which was added to ensure enough space for NUL, but strscpy destination string is guaranteed to be NUL-terminted, therefore, the -1 is not needed. Signed-off-by:

Patch 1-12 converts qede_parse_flow_attr() to use extack, along with all it's static helper functions. qede_parse_flow_attr() is used in two places: - qede_add_tc_flower_fltr() - qede_flow_spec_to_rule() In the latter call site extack is faked in the same way as is done in mlxsw (patch 12). While the conversion is going on, some error messages are silenced in between patch 1-12. If wanted could squash patch 1-12 in a v3, but I felt that it would be easier to review as 12 more trivial patches. Patch 13 and 14, finishes up by converting qede_parse_actions(), and ensures that extack is propagated to it, in both call contexts. v1: https://lore.kernel.org/netdev/20240507104421.1628139-1-ast@fiberby.net/ ==================== Link: https://lore.kernel.org/r/20240508143404.95901-1-ast@fiberby.netSigned-off-by:
