Merge branch 'qed-next' 

Manish Chopra says:

====================
qed/qede: Enhancements

This patch series adds these below features support in qed/qede

1) Ntuple filter configuration [via ethtool -n/N]
2) EEE (energy efficient ethernet) support [ethtool --set-eee/show-eee]
3) Coalescing configuration support for VFs [via ethtool -c/C]

Please consider applying this to "net-next"

V1->V2:
* Fixes below Kbuild test robot warning.
