      bnx2x: Correct EEE statistics gathering · c20cd5d7
      Yuval Mintz authored
      In boards with 4-ports, Tx LPI statistics were gathered incorrectly.
      This patch guarantees that each pmf will only query its own port for
      these statistics.

      Pull networking changes from David S Miller:
       1) Remove the ipv4 routing cache.  Now lookups go directly into the FIB
          trie and use prebuilt routes cached there.
          No more garbage collection, no more rDOS attacks on the routing
          cache.  Instead we now get predictable and consistent performance,
          no matter what the pattern of traffic we service.
          This has been almost 2 years in the making.  Special thanks to
          Julian Anastasov, Eric Dumazet, Steffen Klassert, and others who
          have helped along the way.
          I'm sure that with a change of this magnitude there will be some
          kind of fallout, but such things ought the be simple to fix at this
          point.  Luckily I'm not European so I'll be around all of August to
          fix things :-)
          The major stages of this work here are each fronted by a forced
          merge commit whose commit message contains a top-level description
          of the motivations and implementation issues.
       2) Pre-demux of established ipv4 TCP sockets, saves a route demux on
       3) TCP SYN/ACK performance tweaks from Eric Dumazet.
       4) Add namespace support for netfilter L4 conntrack helpers, from Gao
       5) Add config mechanism for Energy Efficient Ethernet to ethtool, from
          Yuval Mintz.
       6) Remove quadratic behavior from /proc/net/unix, from Eric Dumazet.
       7) Support for connection tracker helpers in userspace, from Pablo
          Neira Ayuso.
       8) Allow userspace driven TX load balancing functions in TEAM driver,
          from Jiri Pirko.
       9) Kill off NLMSG_PUT and RTA_PUT macros, more gross stuff with
          embedded gotos.
      10) TCP Small Queues, essentially minimize the amount of TCP data queued
          up in the packet scheduler layer.  Whereas the existing BQL (Byte
          Queue Limits) limits the pkt_sched --> netdevice queuing levels,
          this controls the TCP --> pkt_sched queueing levels.
          From Eric Dumazet.
      11) Reduce the number of get_page/put_page ops done on SKB fragments,
          from Alexander Duyck.
      12) Implement protection against blind resets in TCP (RFC 5961), from
          Eric Dumazet.
      13) Support the client side of TCP Fast Open, basically the ability to
          send data in the SYN exchange, from Yuchung Cheng.
          Basically, the sender queues up data with a sendmsg() call using
          MSG_FASTOPEN, then they do the connect() which emits the queued up
          fastopen data.
      14) Avoid all the problems we get into in TCP when timers or PMTU events
          hit a locked socket.  The TCP Small Queues changes added a
          tcp_release_cb() that allows us to queue work up to the
          release_sock() caller, and that's what we use here too.  From Eric
      15) Zero copy on TX support for TUN driver, from Michael S. Tsirkin.
