Subject: net: dsa: mv88e6xxx: prefix Global Switch MAC macros
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4b0c481717b9896fa7a778dfd0b197ce8325bd1a;p=openwrt%2Fstaging%2Fblogic.git

net: dsa: mv88e6xxx: prefix Global Switch MAC macros

Prefix and document the Global Switch MAC Address Register macros and
give clear 16-bit register representation.

At the same time, move mv88e6xxx_g1_set_switch_mac in global1.c, where
it belongs.
