[dpdk-dev] [PATCH] net/enic: fix max packet length check

When the device was configured with an explicit maximum packet length,
it would fail if the value was greater than MTU configured in CIMC/UCSM
(plus L2 header length). It should have been compared against maximum
allowed by the device.
Fixes: bb34ffb848a0 ("net/enic: determine max egress packet size and max MTU")
