Subject: netifd: Fix restore of original device settings
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=9d8dd091f8f336b111364ed211165b5ec9842a24;p=oweals%2Fnetifd.git

netifd: Fix restore of original device settings

Don't restore original device settings based on the device settings flags in system_if_down
as device flags are already reset when the device config is deleted.
Therefore move the masking of the relevant original device settings to system_if_up.
