Subject: [patch net-next 4/4] mlxsw: spectrum: Change bridge port attributes only when bridged
Date: Mon,  4 Jan 2016 10:42:26 +0100	[thread overview]
Message-ID: <1451900546-2006-5-git-send-email-jiri@resnulli.us> (raw)
In-Reply-To: <1451900546-2006-1-git-send-email-jiri@resnulli.us>

From: Ido Schimmel <idosch@mellanox.com>

Bridge port attributes are offloaded to hardware when invoked with SELF
flag set, but it really makes no sense to reflect them when port is not
bridged.

Allow a user to change these attribute only when port is bridged and
initialize them correctly when joining or leaving a bridge.
