T48G with WIFI auto provision bug

[freak]

When you are using auto-provision with a T48G the phone looks for a file {MAC}.cfg on a tftp server where {MAC}.cfg is a file which matches the mac address of the ethernet adapter. This works great until you install a yealink wifi dongle. When you install the dongle the phone gets a new mac address from the dongle. Not only is the mac incorrect when you log into the web interface (It's still the wired mac address) it's also wrong on the phone menu system and worst of all the phone still uses the wired mac address to find it's .cfg file. This of course doesn't work at all. The firmware needs fixed to use the proper mac address of the wifi adapter. I've verified this using tcpdump.
