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. --- v2: Based on review and suggestions from Jiri Pirko <j...@resnulli.us>: - 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 ().
