Merge branch 'cxgb4' 

Hariprasad Shenai says:

====================
This patch series provides miscelleneous fixes for Chelsio T4/T5 adapters
related to server entries and server filter entries.

Also, fixes a bug in ULD (Upper Level Driver) like iw_cxgb4 where-in it
calculates wrong tuple values
on T5 adapter. So, a new API cxgb4_select_ntuple is exported so as to enable
Upper Lever Drivers like iw_cxgb4 to correctly calculate tuple values.

The patches series is created agains David Miller's 'net' tree.
And includes patches on cxgb4 and iw_cxgb4 driver.

Patch 8/8 (RDMA-cxgb4-Use-cxgb4_select_ntuple-to-correctly-calc.patch)
has a build dependency on Patch 5/8
(cxgb4-Add-API-to-correctly-calculate-tuple-fields.patch).

Also, Patch 6/8 (RDMA-cxgb4-Calculate-the-filter-server-TID-properly.patch) has
a functional
dependency on Patch 3/8 (cxgb4-Assign-filter-server-TIDs-properly.patch)

We would like to request this patch series to get merged via David Miller's
'net' tree.

We have included all the maintainers of respective drivers. Kindly review the
change and let us know in case of any review comments.

V2 changes:
 - Removed earlier patch which added sftids_in_use counter. However, the counter
   was actually not used anywhere in this patch series.
   Thanks to David Miller for spotting this.
   We have dropped this patch in V2 and will submit a more complete patch which
   uses sftids_in_use counter later on.
 - Fixed a 'checkpatch.pl --strict' warning on Patch 5/8
   (cxgb4-Add-API-to-correctly-calculate-tuple-fields.patch).
 - Removed some un-used #defines from Patch 5/8
   (cxgb4-Add-API-to-correctly-calculate-tuple-fields.patch).
