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" . Signed-off-by: Larry Finger --- John, I hope this fix makes it into 2.6.21. As you have seen from the list, it is a biggie!
