Title:
  Trusty kernel network performance regression

Status in “linux” package in Ubuntu:
  Fix Released
Status in “linux” source package in Trusty:
  Fix Released

Bug description:
  SRU Justification:

  Impact:

  Reduced TCP/IP receive performance for network devices that do not
  split packet headers into skb linear area (e.g., mlx4).  The trusty
  kernel has incorporated

  commit eff44f9cc9a02aad53d568d3ae5020b6792ae4f6
  Author: Jerry Chu <hkchu@xxxxxxxxxx>
  Date:   Wed Dec 11 20:53:45 2013 -0800

      net-gro: Prepare GRO stack for the upcoming tunneling support

  which modifies the GRO frag0 optimization, but unfortunately for some
  cases results in calls to __skb_pull_tail for every packet being
  received via the GRO path.  This causes a reduction in TCP receive
  performance (or, more accurately, an increase in CPU load for TCP
  receive processing, which will cause throughput reduction for CPU
  limited workloads).

  Fix:

  This has already been fixed in mainline in

  commit a50e233c50dbc881abaa0e4070789064e8d12d70
  Author: Eric Dumazet <edumazet@xxxxxxxxxx>
  Date:   Sat Mar 29 21:28:21 2014 -0700

      net-gro: restore frag0 optimization

  The fix has been backported to and verified on the trusty kernel using
  mlx4 devices and iperf; an increase from 7.5 to 8.5 Gb/sec was
  observed when adding the patch, and the relevant portion of perf
  captures show changes in the call paths from:

  Testcase:

  The fix was tested using mlx4 10Gb/sec network devices between two
  arm64 systems using "iperf -s" on one end and "iperf -c" on the other.
  The unmodified kernel reported approximately 7.5 Gb/sec throughput,
  the fixed kernel approximately 8.5 Gb/sec.
