From daf4dd16438b897a44929771c85b9512c2c20412 Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Thu, 2 Dec 2021 08:38:39 -0800 Subject: [PATCH] ice: Refactor spoofcheck configuration functions Add functions to configure Tx VLAN antispoof based on iproute configuration and/or VLAN mode and VF driver support. This is needed later so the driver can control when it can be configured. Also, add functions that can be used to enable and disable MAC and VLAN spoofcheck. Move spoofchk configuration during VSI setup into the SR-IOV initialization path and into the post VSI rebuild flow for VF VSIs.
