Subject: [dpdk-dev] [PATCH v2 04/20] net/bnxt: ulp mapper changes to use tcam search
Date: Thu, 23 Jul 2020 17:26:23 +0530 [thread overview]
Message-ID: <20200723115639.22357-5-somnath.kotur@broadcom.com> (raw)
In-Reply-To: <20200723115639.22357-1-somnath.kotur@broadcom.com>
From: Mike Baucom <michael.baucom@broadcom.com>
modified ulp mappper to use the new tf_search_tcam_entry API.
When search before allocation is requested, mapper calls
tc_search_tcam_entry with the alloc flag.
- On HIT, the result and tcam index is returned.
- On MISS, the tcam index is returned but the result is
created and the tcam entry is set.
- On REJECT, the flow request is rejected.
