Merge branch 'cxgb4-dcb' 

Anish Bhatt says:

====================
cxgb4 DCB updates

The following patchset covers changes to work better with  the userspace
tools cgdcbxd and cgrulesengd and improves firmware support for
host-managed mode.

Also exports traffic class information that was previously not being
exported via dcbnl_ops and unfifies how app selector information is passed
to firmware.
====================
