mlx5 IPsec replay window enhancement and XFRM core statistics

From: Leon Romanovsky <[email protected]>

Hi,

This series does two things at the same time, but they are connected together:
* Rewrite and fix mlx5 IPsec replay window implementation.
* Connect XFRM statistics with offloaded counters to report replay window reason statistics.

First two patches are XFRM core changes to allow reuse of already existing callback to fill all statistics.

Next two patches are fixes to replay window and sequence packet number misconfiguration. They are not urgent and can go to -next.

Rest of the patches are rewrite of mlx5 replay window implementation.

As an example, the end result, after simulating replay window attack with 5 packets:
[leonro@c ~]$ grep XfrmInStateSeqError /proc/net/xfrm_stat
XfrmInStateSeqError 5
[leonro@c ~]$ sudo ip -s x s
<...>
stats:
replay-window 0 replay 5 failed 0

Thanks
