[PATCH net 3/5] nfp: inherit the max_mtu from the PF netdev

[Jakub Kicinski]

From: Dirk van der Merwe <dirk.vanderme...@netronome.com>

The PF netdev is used for data transfer for reprs, so reprs inherit the
maximum MTU settings of the PF netdev.

Fixes: 5de73ee46704 ("nfp: general representor implementation")
