From e0f9956a3862b32ad73869a8e52a33c84aafa46f Mon Sep 17 00:00:00 2001 From: "Chuah, Kim Tatt" Date: Fri, 25 Sep 2020 17:40:41 +0800 Subject: net: stmmac: Add option for VLAN filter fail queue enable Add option in plat_stmmacenet_data struct to enable VLAN Filter Fail Queuing. This option allows packets that fail VLAN filter to be routed to a specific Rx queue when Receive All is also set. When this option is enabled: - Enable VFFQ only when entering promiscuous mode, because Receive All will pass up all rx packets that failed address filtering (similar to promiscuous mode). - VLAN-promiscuous mode is never entered to allow rx packet to fail VLAN filters and get routed to selected VFFQ Rx queue.
