    net: Move check for multiple vlans to drivers

offloads were broken in Q-in-Q vlans. The biggest problem was
that tcp checksum offload was enabled and used for all hardware,
while most of the supported HW (mostly old HW and some newer ones)
don't support it.  As a result, tcp connections could not be
established when using Q-in-Q vlans.

This short series corrects this by disabling checksum offload
support on packets sent through Q-in-Q vlans.  It is up to individual
drivers to enable it properly through ndo_features_check if they
have some support for Q-in-Q vlans.


Vladislav Yasevich (3):
  vlan: Fix Q-in-Q vlan support.
  be2net: Fix offload features for Q-in-Q packets
  virtio-net: enable TSO/checksum offloads for Q-in-Q vlans
