[PATCH] bcm43xx: check for valid MAC address in SPROM

[PATCH] bcm43xx: check for valid MAC address in SPROM

[Stefano Brivio]

Please apply to 2.6.17, as it fixes a problem that prevents bcm43xx devices
which support 802.11a in addition to 802.11b/g from working, as the MAC
address isn't detected correctly. This applies to 2.6.17-rc3.

Check for valid MAC address in SPROM fields instead of relying on PHY type
while setting the MAC address in the networking subsystem, as some devices
have multiple PHYs.
