Subject: [PATCH 4.14 024/105] bnx2x: Remove configured vlans as part of unload sequence.
Date: Fri, 11 Jan 2019 15:13:55 +0100	[thread overview]
Message-ID: <20190111131105.377370861@linuxfoundation.org> (raw)
In-Reply-To: <20190111131102.899065735@linuxfoundation.org>

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 04f05230c5c13b1384f66f5186a68d7499e34622 ]

Vlans are not getting removed when drivers are unloaded. The recent storm
firmware versions had added safeguards against re-configuring an already
configured vlan. As a result, PF inner reload flows (e.g., mtu change)
might trigger an assertion.
This change is going to remove vlans (same as we do for MACs) when doing
a chip cleanup during unload.
