We utilize many Routerboard 751's and discovered that our latest batch of RB751's would not initialize the wireless radio. We have determined Mikrotik has changed where the mac address was located inside hardconfig. As such we utilize "routerboot_find_tag" to find the location of the mac address. We should remove "RB751_MAC_ADDRESS_OFFSET" as it is ambiguous by machine manufacturing date. The newer batch of RB751's that we received had a RB751_MAC_ADDRESS_OFFSET 0x10.
