[net-next PATCH 02/10] net: dsa: realtek: rtl8365mb: set STP state to disabled early
Posted by Luiz Angelo Daros de Luca 2 days, 9 hours ago
From: Alvin Šipraga <alsi@bang-olufsen.dk>

Since we are going around and manipulating a number of port settings
during setup, it's safer to assume that the port is disabled to begin
with. This is purely defensive.
