Hi Andrew,

Hi Shannon

In my experience the driver typically tells the NIC about the current
max_frame size (e.g. MTU + ETH_HLEN), the NIC only copies max_frame bytes,
and the NIC returns an error indication on a packets that had more than
max_frame.

Having played around with a few different NICs for DSA, it seems more
like 75% don't care about the 'MRU' and will happily accept bigger
frames.

Anyway, it does not hurt to drop received frames bigger than what you
can transmit.
