[dpdk-dev] [PATCH v2 10/12] net/bnxt: add cache table type for TCAM lookup

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

From: Mike Baucom <michael.baucom@broadcom.com>

In order to re-use allocated resources and reduce search complexity for
simple keys, a generic software cache table was added for the TCAM. The
implementation is specifically only for keys that can be compressed to
less than 16 bits.  The keys are generated using the same mechanisms as
other search tables, but the table type is set to a cache that mirrors
the actual TCAM table. The allocated result fields are stored in the
cache entry and can be used for subsequent searches in future tables.
