6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Leon Romanovsky <leonro@xxxxxxxxxx>
[ Upstream commit 2d9dac5559f8cc4318e6b0d3c5b71984f462620b ]
IPsec SA statistics presents successfully decrypted and encrypted
packet and bytes, and not total handled by this SA. So update the
calculation logic to take into account failures.
Fixes: 6fb7f9408779 ("net/mlx5e: Connect mlx5 IPsec statistics with XFRM core")
