[dpdk-dev] net/enic: fix max packet length check
Commit Message
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")

Applied, thanks
