and default every PHY to 5 seconds (what we used before). If we find
Gig-E media on a PHY, bump it to 10 seconds, since it can take 5
seconds just to negotiate a Gig-E link.
802.3 doens't specify ANAR or ANLPAR bits for GMII. Need to
use PHY-specific registers for this, for now, which means we
need specific drivers for the Gigabit-capable PHYs (I think the
most common is the BCM5400).
instead of discrete function pointers, and extend this to include
a "reset" entry point. Make sure any PHY-specific reset routine is
always used, and provide one for the LXT-970 which disables MII
interrupts (as is done for a few other PHYs we have drivers for).
PHYs we don't have specific drivers for. While this will not give
optimum operation, it will allow network interface drivers to at least
function while drivers for their specific PHYs are written.
