Subject: [net 04/13] net/mlx5e: Claim TC hw offloads support only under a proper build config
Date: Mon, 19 Nov 2018 15:41:19 -0800 [thread overview]
Message-ID: <20181119234128.6948-5-saeedm@mellanox.com> (raw)
In-Reply-To: <20181119234128.6948-1-saeedm@mellanox.com>
From: Or Gerlitz <ogerlitz@mellanox.com>
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.
Fixes: e8f887ac6a45 ('net/mlx5e: Introduce tc offload support')
