Subject: [PATCH net-next 06/11] net: dsa: Add support for querying supported bridge flags
Date: Tue, 18 Jul 2017 17:20:19 +0300	[thread overview]
Message-ID: <1500387624-4361-7-git-send-email-arkadis@mellanox.com> (raw)
In-Reply-To: <1500387624-4361-1-git-send-email-arkadis@mellanox.com>

The DSA drivers do not support bridge flags offload. Yet, this attribute
should be added in order for the bridge to fail when one tries set a
flag on the port, as explained in commit dc0ecabd6231 ("net: switchdev:
Add support for querying supported bridge flags by hardware").
