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.
