    Subject[PATCH 5.10 006/145] net: systemport: set dev->max_mtu to UMAC_MAX_MTU_SIZE
    Date
    From: Florian Fainelli <f.fainelli@gmail.com>

    [ Upstream commit 54ddbdb024882e226055cc4c3c246592ddde2ee5 ]

    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")
