SVN rev 213812 on 2010-10-13 22:29:48Z by yongari
Fix a regression introduced in r213710. r213710 removed the use of
auto polling such that it made all controllers obtain link status
information from the state of the LNKRDY input signal. Broadcom
recommends disabling auto polling such that driver should rely on
PHY interrupts for link status change indications. Unfortunately it
seems some controllers(BCM5703, BCM5704 and BCM5705) have PHY
related issues so Linux took other approach to workaround it.
bge(4) didn't follow that and it used to enable auto polling to
workaround it. Restore this old behavior for BCM5700 family
controllers and BCM5705 to use auto polling. For BCM5700 and
BCM5701, it seems it does not need to enable auto polling but I
restored it for safety.
Special thanks to marius who tried lots of patches with patience.
