Subject: [RFC net-next 2/3] net: dsa: qca8k: enable assisted learning on CPU port
Date: Sat,  7 Aug 2021 20:07:25 +0800	[thread overview]
Message-ID: <20210807120726.1063225-3-dqfext@gmail.com> (raw)
In-Reply-To: <20210807120726.1063225-1-dqfext@gmail.com>

Enable assisted learning on CPU port to fix roaming issues.

Although hardware learning is available, it won't work well with
software bridging fallback or multiple CPU ports.
