      net/mlx4_en: Add ethtool statistics for XDP cases · 15fca2c8
      Tariq Toukan authored
      
      
      XDP statistics are reported in ethtool, in total and per ring,
      as follows:
      - xdp_drop: the number of packets dropped by xdp.
      - xdp_tx: the number of packets forwarded by xdp.
      - xdp_tx_full: the number of times an xdp forward failed
      	due to a full tx xdp ring.
      
      In addition, all packets that are dropped/forwarded by XDP
      are no longer accounted in rx_packets/rx_bytes of the ring,
      so that they count traffic that is passed to the stack.

      net/mlx4_en: Refactor the XDP forwarding rings scheme · 67f8b1dc
      Tariq Toukan authored
      
      
      Separately manage the two types of TX rings: regular ones, and XDP.
      Upon an XDP set, do not borrow regular TX rings and convert them
      into XDP ones, but allocate new ones, unless we hit the max number
      of rings.
      Which means that in systems with smaller #cores we will not consume
      the current TX rings for XDP, while we are still in the num TX limit.
      
      XDP TX rings counters are not shown in ethtool statistics.
      Instead, XDP counters will be added to the respective RX rings
      in a downstream patch.
      
      This has no performance implications.

      sctp: clean up sctp_packet_transmit · e4ff952a
      Xin Long authored
      
      
      After adding sctp gso, sctp_packet_transmit is a quite big function now.
      
      This patch is to extract the codes for packing packet to sctp_packet_pack
      from sctp_packet_transmit, and add some comments, simplify the err path by
      freeing auth chunk when freeing packet chunk_list in out path and freeing
      head skb early if it fails to pack packet.

      Netfilter updates for net-next
      
      The following patchset contains Netfilter updates for your net-next
      tree. This includes better integration with the routing subsystem for
      nf_tables, explicit notrack support and smaller updates. More
      specifically, they are:
      
      1) Add fib lookup expression for nf_tables, from Florian Westphal. This
         new expression provides a native replacement for iptables addrtype
         and rp_filter matches. This is more flexible though, since we can
         populate the kernel flowi representation to inquire fib to
         accomodate new usecases, such as RTBH through skb mark.
      
      2) Introduce rt expression for nf_tables, from Anders K. Pedersen. This
         new expression allow you to access skbuff route metadata, more
         specifically nexthop and classid fields.
      
      3) Add notrack support for nf_tables, to skip conntracking, requested by
         many users already.
      
      4) Add boilerplate code to allow to use nf_log infrastructure from
         nf_tables ingress.
      
      5) Allow to mangle pkttype from nf_tables prerouting chain, to emulate
         the xtables cluster match, from Liping Zhang.
      
      6) Move socket lookup code into generic nf_socket_* infrastructure so
         we can provide a native replacement for the xtables socket match.
      
      7) Make sure nfnetlink_queue data that is updated on every packets is
         placed in a different cache from read-only data, from Florian Westphal.
      
      8) Handle NF_STOLEN from nf_tables core, also from Florian Westphal.
      
      9) Start round robin number generation in nft_numgen from zero,
         instead of n-1, for consistency with xtables statistics match,
         patch from Liping Zhang.
      
      10) Set GFP_NOWARN flag in skbuff netlink allocations in nfnetlink_log,
          given we retry with a smaller allocation on failure, from Calvin Owens.
      
      11) Cleanup xt_multiport to use switch(), from Gao feng.
      
      12) Remove superfluous check in nft_immediate and nft_cmp, from
          Liping Zhang.
