Subject: netifd: Remove superfluous system_if_resolve calls
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fnetifd.git;a=commitdiff_plain;h=b3a698e7b6c099203dcb4227a21813948b176e3b

netifd: Remove superfluous system_if_resolve calls

Don't resolve the ifindex of the parent device again
when adding vlandev and macvlan devices as the ifindex
has already been resolved.
