Subject: [PATCH] net/mlx5e: Align IPsec ASO result memory to be as required by
hardware
References: bsc#1012628
Patch-mainline: 6.2.3
Git-commit: f2b6cfda76d2119871e10fa01ecdc7178401ef22
[ Upstream commit f2b6cfda76d2119871e10fa01ecdc7178401ef22 ]
Hardware requires an alignment to 64 bytes to return ASO data. Missing
this alignment caused to unpredictable results while ASO events were
generated.
Fixes: 8518d05b8f9a ("net/mlx5e: Create Advanced Steering Operation object for IPsec")
