From e326f2f13b209d56782609e833b87cb497e64b3b Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Wed, 2 Jul 2014 17:36:23 +0300 Subject: [PATCH] net/mlx4_en: Don't configure the HW vxlan parser when vxlan offloading isn't set The add_vxlan_port ndo driver code was wrongly testing whether HW vxlan offloads are supported by the device instead of checking if they are currently enabled. This causes the driver to configure the HW parser to conduct matching for vxlan packets but since no steering rules were set, vxlan packets are dropped on RX. Fix that by doing the right test, as done in the del_vxlan_port ndo handler. Fixes: 1b136de ('net/mlx4: Implement vxlan ndo calls') Signed-off-by: Or Gerlitz Signed-off-by: David S.
