[PATCH net-next 0/7] eth: fbnic: support RSS contexts and ntuple filters

[Jakub Kicinski <kuba@kernel.org>]

Add support for RSS contexts and ntuple filters in fbnic.
The device has only one context, intended for use by TCP zero-copy Rx.

First two patches add a check we seem to be missing in the core,
to avoid having to copy it to all drivers.
