[PATCH v6 00/33] Intel PMD drivers Rx cleanup

[Anatoly Burakov]

There is certain amount of duplication between different ixgbe, i40e, ice, and
iavf. This patchset specifically focuses on laying groundwork for deduplicating
the Rx side of things - providing common queue definitions, using common Rx
descriptor formats, and some low hanging fruit in terms of Rx code
deduplication, including vectorized implementations.

The first bunch of patches focus on small cleanups:

- variable renames
- definition renames
- using one definition for 16-byte descriptors instead per-driver
- fixing some cruft in IXGBE headers and source code
- refactoring of IXGBE vector code
- removing support for 16-byte descriptors from IAVF

Starting with patch 23 comes the meat of the patchset:

- creating common Rx queue structure
- unifying Rx rearm code to make use of new unified structures and definitions
- expanding Rx rearm code to have SSE, AVX2, and AVX512 implementations

At the end, there are a couple of patches that unify Rx and Tx mbuf recycle
for some drivers, but more work is needed on that front because we only touch
two drivers in each case - the others do have them, but they're implemented
differently from the ones that were deduplicated.

v6:
- Fix compile issue with `ixgbe_tx_desc_done`
- Address various nitpicks in review

v5:
- Added refactors in IXGBE
- Addressed various bits of feedback
- Removed support for 16-byte descriptors from IAVF

v3 -> v4:
- Added a lot of cleanups to the patchset
- Moved to using unified Rx descriptor definitions
- Using a single compilation flag to support 16-byte descriptors
- Fixes for whitespace, syntax, etc.
