Subject: [RFC net-next 3/3] net: dsa: tag_qca: set offload_fwd_mark
Date: Sat,  7 Aug 2021 20:07:26 +0800	[thread overview]
Message-ID: <20210807120726.1063225-4-dqfext@gmail.com> (raw)
In-Reply-To: <20210807120726.1063225-1-dqfext@gmail.com>

As we offload flooding and forwarding, set offload_fwd_mark according to
Atheros header's type.
