     True, but I think it is already used for Rx already as concept, I believe 
the
     intention will be clear enough. Do you think will be more clear if we pick 
a
     DPDK specific variable name?

Maybe use MRU - Max Receive Unit.

It can be an option, but this patch unifies 'max_rx_pkt_len' & 'mtu' => mtu,
if we switch to 'mru', we should switch all usage to 'mru', including
'rte_eth_dev_set_mtu()' API name change, to not cause a new confusion between
'mru' & 'mtu' difference.

Does 'mtu' really cause this much confusion to do all this change?

Reconsidering it I see no better options. Yes, mtu is a bit confusing
in Rx configuration, but just a bit.
