Subject: [net 02/11] net/mlx5e: Add missing capability check for uplink follow
Date: Thu, 7 Jan 2021 12:28:36 -0800 [thread overview]
Message-ID: <20210107202845.470205-3-saeed@kernel.org> (raw)
In-Reply-To: <20210107202845.470205-1-saeed@kernel.org>
From: Aya Levin <ayal@nvidia.com>
Expose firmware indication that it supports setting eswitch uplink state
to follow (follow the physical link). Condition setting the eswitch
uplink admin-state with this capability bit. Older FW may not support
the uplink state setting.
Fixes: 7d0314b11cdd ("net/mlx5e: Modify uplink state on interface up/down")
