Subject: ramips: mt7621: bringup dsa master on preinit
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=4d979a4d1969b59e462ea4633eeb8c69111261c5;p=oweals%2Fopenwrt.git

ramips: mt7621: bringup dsa master on preinit

DSA requires master netdev to be up before any of its slave ports.
Bring it up during preinit so that the first lan port can be used
on failsafe.
