Subject: [PATCH AUTOSEL 4.9 22/34] mv88e6060: disable hardware level MAC learning
Date: Wed, 12 Dec 2018 23:31:48 -0500 [thread overview]
Message-ID: <20181213043200.76295-22-sashal@kernel.org> (raw)
In-Reply-To: <20181213043200.76295-1-sashal@kernel.org>
From: Anderson Luiz Alves <alacn1@gmail.com>
[ Upstream commit a74515604a7b171f2702bdcbd1e231225fb456d0 ]
Disable hardware level MAC learning because it breaks station roaming.
When enabled it drops all frames that arrive from a MAC address
that is on a different port at learning table.
