Merge branch 'cls_flower-port-masks'

Or Gerlitz says:

====================
net/sched: cls_flower: Add ports masks

This series adds the ability to specify tcp/udp ports masks
for TC/flower filter matches.

I also removed an unused fields from the flower keys struct
and clarified the format of the recently added vlan attibutes.

v1--> v2 changes:

 * fixes typo in patch #2 title and change log (Sergei)
 * added acks provided by Jiri on v1

FWIW, by mistake the cover letter of V1 (but not the patches)
carried V2 tag, hope this doesn't create too much confusion.
====================
