[PATCH net-next v3 0/5] cxgb4: add support for offloading TC u32 filters

This series of patches add support to offload TC u32 filters onto
Chelsio NICs.

Patch 1 moves current common filter code to separate files
in order to provide a common api for performing packet classification
and filtering in Chelsio NICs.

Patch 2 enables filters for normal NIC configuration and implements
common api for setting and deleting filters.

Patches 3-5 add support for TC u32 offload via ndo_setup_tc.

v3:

Based on review and suggestion from David Miller [off-list ref]
- Fixed all local variable declarations by placing them in longest line
  first and shortest line last order.

v2:

Based on review and suggestions from Jiri Pirko [off-list ref]:
- Replaced macros S and U with appropriate static helper functions.
- Moved completion code for set and delete filters to respective
  functions cxgb4_set_filter() and cxgb4_del_filter().  Renamed the
  original functions to __cxgb4_set_filter() and __cxgb4_del_filter()
  in case synchronization is not required.
- Dropped debugfs patch.
- Merged code for inserting and deleting u32 filters into a single
  patch.
- Reworked and fixed bugs with traversing the actions list.
- Removed all unnecessary extra ().
