From: Vivien Didelot Date: Mon, 9 May 2016 17:22:53 +0000 (-0400) Subject: net: dsa: mv88e6xxx: factorize GLOBAL_MONITOR_CONTROL setup X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b0745e87943b40734e6c341dcf47a6ec80ee4346;p=linux-beck.git net: dsa: mv88e6xxx: factorize GLOBAL_MONITOR_CONTROL setup All switch drivers configure the GLOBAL_MONITOR_CONTROL register with slightly changes. Assume the setup of the upstream port, and configure it as the port to which ingress and egress and ARP monitor frames are to be sent. Signed-off-by: Vivien Didelot Signed-off-by: David S.
