From 5eff6dadb9f466d15692cc5dd45e1015bf0ec987 Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Thu, 15 Jan 2015 15:28:54 +0200 Subject: [PATCH] net/mlx4: Don't disable vxlan offloads under DMFS-A0 optimized steering Except for VXLAN steering rules, all offloads should work as they were under plain DMFS mode. Fix that by enabling all the offloads under DMFS-A0 mode, except for VXLAN steering rules. Fixes: d57febe1a478 "net/mlx4: Add A0 hybrid steering" Signed-off-by: Or Gerlitz Signed-off-by: David S.
