ar71xx: initial support for Mikrotik RB751G-2HnD and RB751U-2HnD
Great collaboration on these two fantastic routers on the openwrt forum: https://forum.openwrt.org/viewtopic.php?id=32320 Above all kudos to aryufan. Well done and thank you everyone else who contributed. To-Do: LED for wlan is not yet activated To-Do: TxPower over 20dBm (RB751U) or 22dBm (RB751G) are not accepted by the router Signed-off-by: Hanno Schupp <hanno.schupp@gmail.com> [juhosg: fix line wrapped patch, fix checkpatch errors, add missing kernel patches] SVN-Revision: 31208
