net: vrf: remove MTU limits for vrf device

liuhangbin · davem330 · commit ad49bc6361ca · 2019-02-21T13:10:08.000-08:00
Similiar to commit e94cd81 ("net: remove MTU limits for dummy and ifb device"), MTU is irrelevant for VRF device. We init it as 64K while limit it to [68, 1500] may make users feel confused.
