====================
cxgb4: add hash-filter support to tc-flower offload

This series of patches add support to create hash-filters; a.k.a
exact-match filters, to tc-flower offload.  T6 supports creating
~500K hash-filters in hw and can theoretically be expanded up to
~1 million.

Patch 1 fetches and saves the configured hw filter tuple field shifts
and filter mask.

Patch 2 initializes the driver to use hash-filter configuration.

Patch 3 adds support to create hash filters in hw.

Patch 4 adds support to delete hash filters in hw.

Patch 5 adds support to retrieve filter stats for hash filters.

Patch 6 converts the flower table to use rhashtable instead of
static hlist.

Patch 7 finally adds support to create hash filters via tc-flower
offload.
