From cd753c108db26ab83e53b8867a0b980cfab193ce Mon Sep 17 00:00:00 2001 From: Leon Romanovsky Date: Sun, 19 Feb 2023 11:09:10 +0200 Subject: [PATCH] net/mlx5e: Align IPsec ASO result memory to be as required by hardware [ 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.
