[PATCH] bcm43xx: Fix code for spec changes of 2/7/2007

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The specifications for the bcm43xx driver have been modified. This patch
incorporates these changes in the code, which results in the BCM4311 and
BCM4312 working. The name of one of the PHY parameters, previously known
as "version", has been changed to "analog core version" .

John,

I hope this fix makes it into 2.6.21. As you have seen from the list, it is a biggie!
