Merge branch 'tcp-move-few-fields-for-data-locality'
Eric Dumazet says:
====================
tcp: move few fields for data locality
After recent additions (PSP and AccECN) I wanted to make another
round on fields locations to increase data locality.
This series manages to shrink TCP and TCPv6 objects by 128 bytes,
but more importantly should reduce number of touched cache lines
in TCP fast paths.
There is more to come.
v2: removed tcp CACHELINE_ASSERT_GROUP_SIZE after a kernel build bot
reported an error.
