Subject: [PATCH] net/mlx5e: Connect mlx5 IPsec statistics with XFRM core
Fill integrity, replay and bad trailer counters.
As an example, 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
