[PATCH net-next v2 02/10] net: dsa: lan9303: Do not disable/enable switch fabric port 0 at startup

From: Egil Hjelmeland
Date: Tue Jul 25 2017 - 14:06:01 EST


For some mysterious reason enable switch fabric port 0 TX fails to
work, when the TX has previous been disabled. Resolved by not
disable/enable switch fabric port 0 at startup. Port 1 and 2 are
still disabled in early init.
