Understanding RX_OFFLOAD_VLAN_EXTEND

[Ivan Malov]

Hi!

We have a hard time figuring out what the API contract of
RX_OFFLOAD_VLAN_EXTEND might be. The best educated guess
we can make is that the feature might have something to
do with identifying VLAN packets and extracting TCI
without stripping the tags from incoming packets.

Is this understanding correct?

You see, things aren't helped by the offload bit having
almost no commentary. Such could've shed light on its
meaning. Perhaps this gap in documentation should
be addressed somehow. Any opinions?

Thank you.
