Merge branch 'mlx4-order-0-allocations-and-page-recycling'
Eric Dumazet says:
====================
mlx4: order-0 allocations and page recycling
As mentioned half a year ago, we better switch mlx4 driver to order-0
allocations and page recycling.
This reduces vulnerability surface thanks to better skb->truesize
tracking and provides better performance in most cases.
(33 Gbit for one TCP flow on my lab hosts)
I will provide for linux-4.13 a patch on top of this series,
trying to improve data locality as described in
https://www.spinics.net/lists/netdev/msg422258.html
v2 provides an ethtool -S new counter (rx_alloc_pages) and
code factorization, plus Tariq fix.
v3 includes various fixes based on Tariq tests and feedback
from Saeed and Tariq.
v4 rebased on net-next for inclusion in linux-4.12, as requested
by Tariq.
Worth noting this patch series deletes ~250 lines of code ;)
