Hi,

after running some experiments, we realised that using VLAN support in
Linux caused some overhead. It turned out to be that the offloading
features of our NIC (tso, sg, checksum offloading) were not beeing
used.

After digging a little bit in the code, we realised that the VLAN code
did not set the features parameter of the net_device structure for the
virtual interface. Attached is a patch with a suggested solution to
this problem.

Please let us know if this is an acceptable patch.

Thanks,
Olivier Crameri, HP Labs

Patch needs to include "Developer's Certificate of Origin"
see Documentation/SubmittingPatches section 11.

Patch should not be sent as an attachment (if at all possible).

Skip the marque comment. It is standard practice now to use the revision
control system change log for attribution.

Please handle all the current offload features including GSO.
