From b26f489245b3cf0c06d09a10a8cbdd426af94df6 Mon Sep 17 00:00:00 2001 From: Steffen Klassert Date: Thu, 12 Sep 2019 13:01:44 +0200 Subject: [PATCH] ixgbe: Fix secpath usage for IPsec TX offload. [ Upstream commit f39b683d35dfa93a58f1b400a8ec0ff81296b37c ] The ixgbe driver currently does IPsec TX offloading based on an existing secpath. However, the secpath can also come from the RX side, in this case it is misinterpreted for TX offload and the packets are dropped with a "bad sa_idx" error. Fix this by using the xfrm_offload() function to test for TX offload.
