[PATCH v2] ksz884x: fix mtu for VLAN

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

The Ethernet header does not account for the addition of a VLAN header.
Full size Ethernet frames containing VLAN header are not processed
because the frame is larger than the resulting hw mtu.
