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

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:
7.17% iperf [kernel.kallsyms] [k] __pskb_pull_tail
|
--- __pskb_pull_tail
|
|--48.03%-- tcp_gro_receive
| tcp4_gro_receive
| inet_gro_receive

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.
