Merge branch 'qed-ethtool-rx-flow-classification-enhancements'

Manish Chopra says:

====================
qed*: ethtool rx flow classification enhancements.

This series re-structures the driver's ethtool rx flow
classification flow, following that it adds other flow
profiles and rx flow classification enhancements
via "ethtool -N/-U"

Please consider applying this to "net-next"
