From c0071be0e16c461680d87b763ba1ee5e46548fde Mon Sep 17 00:00:00 2001 From: Emeel Hakim Date: Mon, 31 Oct 2022 11:07:59 +0200 Subject: [PATCH] net/mlx5e: MACsec, remove replay window size limitation in offload path Currently offload path limits replay window size to 32/64/128/256 bits, such a limitation should not exist since software allows it. Remove such limitation.
