From 4bdf89e85ed3881e8c40510ebad918dded9e5831 Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Fri, 24 Apr 2020 13:16:15 -0700 Subject: [PATCH] igc: Fix NFC rule overwrite cases When the 'loc' argument is passed in ethtool, the input rule overwrites any rule present in that location. In this situation we must disable the old rule otherwise it is left enabled in hardware. This patch fixes the issue by always calling igc_disable_nfc_rule() when deleting the old rule, no matter the value of 'input' argument.
