Subject: [PATCH net-next] net: dsa: mt7530: enable MTU normalization
Date: Fri, 11 Dec 2020 01:03:22 +0800 [thread overview]
Message-ID: <20201210170322.3433-1-dqfext@gmail.com> (raw)
MT7530 has a global RX length register, so we are actually changing its
MRU.
Enable MTU normalization for this reason.
