Subject: [PATCH net] net: systemport: set dev->max_mtu to UMAC_MAX_MTU_SIZE
Date: Fri, 18 Dec 2020 09:38:43 -0800	[thread overview]
Message-ID: <20201218173843.141046-1-f.fainelli@gmail.com> (raw)

The driver is already allocating receive buffers of 2KiB and the
Ethernet MAC is configured to accept frames up to UMAC_MAX_MTU_SIZE.

Fixes: bfcb813203e6 ("net: dsa: configure the MTU for switch ports")
