[PATCH] driver/i40e: enable max frame at port level

[wenxuanx . wu]

From: Wenxuan Wu <wenxuanx...@intel.com>

This fix resolve max frame size can only be set when link is up.

hw.type would result in different behavior:
For X710, max frame size can be set regardless of link status.
For X722, link up should be guaranteed.
