[PATCHv2 net 0/4] Implement ndo_gso_check() for vxlan nics

[Joe Stringer]

Most NICs that report NETIF_F_GSO_UDP_TUNNEL support VXLAN, and not other
UDP-based encapsulation protocols where the format and size of the header may
differ. This patch series implements a generic ndo_gso_check() for detecting
VXLAN, then reuses it for these NICs.

Implementation shamelessly stolen from Tom Herbert (with minor fixups):

v2: Drop i40e/fm10k patches (code diverged; handling separately).
    Refactor common code into vxlan_gso_check() helper.
    Minor style fixes.

Joe Stringer (4):
  net: Add vxlan_gso_check() helper
  be2net: Implement ndo_gso_check()
  net/mlx4_en: Implement ndo_gso_check()
  qlcnic: Implement ndo_gso_check()
