Log:
Remove a redundant write of the firmware reset magic number. It
looks to have been added erroneously, and it causes problems on
some chips. A larger change is needed to do this write at a more
appropriate place, but that change requires reworking the ASF
logic. That will be worked on in the future.

I am still getting firmware handshake timeouts and/or watchdog
timeouts. Most importantly it panics or get witness warnings (lots
of 'memory modified after free'). Panic goes like this (while
kldunload if_bge with dhclient enabled):
brgphy0: detached
miibus0: detached
bge0: firmware handshake timed out, found 0x4b657654
bge0: firmware handshake timed out, found 0x4b657654

As you can see the packet length is really bogus. I am wondering if
the chip is actually initialized correctly to begin with.

Does it work correctly before you do the unload?
