Subject: MI424WR - add rev D support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b891eec7001663f8ec4ca4a141ad31ea78163350;p=openwrt%2Fstaging%2Fwigyori.git

MI424WR - add rev D support

Add support for revision D of the MI424WR.
Rev D swaps LAN & WAN ports so this patch maintains
eth0 for LAN and eth1 for WAN. For details on rev D usage,
see http://wiki.openwrt.org/toh/actiontec/mi424wr
