From: Somnath Kotur <somnath.kotur@broadcom.com> To: dev@dpdk.org Cc: ferruh.yigit@intel.com Subject: [dpdk-dev] [PATCH v2 13/20] net/bnxt: ulp mapper changes to use tbl search Date: Thu, 23 Jul 2020 17:26:32 +0530 Message-ID: <20200723115639.22357-14-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_tbl_entry API. When search before allocation is requested, mapper calls tc_search_tbl_entry with the alloc flag. - On HIT, the result and table index is returned. - On MISS, the table index is returned but the result is created and the table entry is set. - On REJECT, the flow request is rejected.
