Hi Andy !

I've been looking at porting various drivers (EMAC, sungem,
spider_net, ...) to the generic PHY stuff. However, I have one
significant problem here.

One solution would be to change it to use a mutex instead of a lock as
well, though that would change the requirements of where phy_start/stop
can be called, and use a delayed work queue instead of a timer.

Wouldn't this change also allow it to be used with USB Ethernet devices?
I was looking at porting the asix.c drive to use the PHY layer but the
locking killed that effort since USB devices can't do spinlocks without
hosing things up.
