eth_dev_validate_mtu, introduced in 990912e676e, validates configured
MTU plus overhead against max_rx_pktlen.
Since TAP is a virtual device, it should support as big MTU as possible.

In all your tries at the patch, you must not have run checkpatch because
it would have informed you that Signed-off-by (a.k.a Developers Certificate of Origin)
is required for any DPDK patch to be accepted.

Please add Signed-off-by and fix the cast.
