====================
mlx5 Software steering, New features and optimizations

This patch series brings various SW steering features, optimizations and
debug-ability focused improvements.

 1) Expose debugfs for dumping the SW steering resources
 2) Removing unused fields
 3) support for matching on new fields
 4) steering optimization for RX/TX-only rules
 5) Make Software steering the default steering mechanism when
    available, applies only to Switchdev mode FDB

From Yevgeny Kliteynik and Muhammad Sammar:

 - Patch 1 fixes an error flow in creating matchers
 - Patch 2 fix lower case macro prefix "mlx5_" to "MLX5_"
 - Patch 3 removes unused struct member in mlx5dr_matcher
 - Patch 4 renames list field in matcher struct to list_node to reflect the
   fact that is field is for list node that is stored on another struct's lists
 - Patch 5 adds checking for valid Flex parser ID value
 - Patch 6 adds the missing reserved fields to dr_match_param and aligns it to
   the format that is defined by HW spec
 - Patch 7 adds support for dumping SW steering (SMFS) resources using debugfs
   in CSV format: domain and its tables, matchers and rules
 - Patch 8 adds support for a new destination type - UPLINK
 - Patch 9 adds WARN_ON_ONCE on refcount checks in SW steering object destructors
 - Patches 10, 11, 12 add misc5 flow table match parameters and add support for
   matching on tunnel headers 0 and 1
 - Patch 13 adds support for matching on geneve_tlv_option_0_exist field
 - Patch 14 implements performance optimization for for empty or RX/TX-only
   matchers by splitting RX and TX matchers handling: matcher connection in the
   matchers chain is split into two separate lists (RX only and TX only), which
   solves a usecase of many RX or TX only rules that create a long chain of
   RX/TX-only paths w/o the actual rules
 - Patch 15 ignores modify TTL if device doesn't support it instead of
   adding and unsupported action
 - Patch 16 sets SMFS as a default steering mode
