[RFC net-next 0/6] net: ethtool: support including Flow Label in the flow hash for RSS

[Jakub Kicinski <kuba@kernel.org>]

Add support for using IPv6 Flow Label in Rx hash computation
and therefore RSS queue selection.

Michael, Pavan, could you please give this series a whirl?
I see the capability bit in bnxt but none of the devices
I have access to seem to expose it. Note the test in the
last patch which you should be able to run. ethtool with
the support: https://github.com/kuba-moo/ethtool
