Subject: [PATCH net 0/3] Fix MTU related issues

As suggested by Alexander Lobakin before, I follows the behavior when
computing MTU size as other drivers do. Adding a second VLAN HLEN could
solve the issue. I have some i40e and ixgbe drivers running on the servers,
so I choose to fix both of them.

Besides, I resent the first patch because the third patch is wrote based
on the first patch. It's relatively for maintainers to handle the
patchset, I think.

Jason Xing (3):
  ixgbe: allow to increase MTU to 3K with XDP enabled
  i40e: add double of VLAN header when computing the max MTU
  ixgbe: add double of VLAN header when computing the max MTU
