From 077ecd785d90c6cbba08d719faa4be8561aa0a1e Mon Sep 17 00:00:00 2001 From: Or Gerlitz Date: Thu, 18 Oct 2018 12:31:27 +0200 Subject: [PATCH] net/mlx5e: Claim TC hw offloads support only under a proper build config Currently, we are only supporting tc hw offloads when the eswitch support is compiled in, but we are not gating the adevertizment of the NETIF_F_HW_TC feature on this config being set. Fix it, and while doing that, also avoid dealing with the feature on ethtool when the config is not set.
