From: Sunil Kumar Kori Date: Mon, 13 Jan 2020 06:16:44 +0000 (+0530) Subject: net/octeontx: add unicast MAC filter X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e4373bf1b3f5;p=dpdk.git net/octeontx: add unicast MAC filter At BGX, DMAC filter table can be enabled to allow defined hosts. Patch implements 'mac_addr_add' and 'mac_addr_remove' ops to add/remove MAC filters which uses BGX DMAC filter table.
