It is best to allow a little time for the reset to settle in before
...
we start polling the BMCR again. Greg Woods noted on tech-net@
that the DP83840A manual states that there should be a 500us delay
between asserting software reset and attempting MII serial operations.
I've also noted that a DP83815 can get into a bad state on cable
removal and reinsertion if we do not delay here.
This may well address PR/16346, and I seem to recall occasional
reports of auto-negotiation and flaky kinds of errors that this
might also alleviate.

Make the number of ticks between auto-negotiation tries PHY-specific,

Gig-E media on a PHY, bump it to 10 seconds, since it can take 5

802.3 doens't specify ANAR or ANLPAR bits for GMII. Need to

need specific drivers for the Gigabit-capable PHYs (I think the
most common is the BCM5400).

interrupts (as is done for a few other PHYs we have drivers for).

New callout mechanism with two major improvements over the old
...
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
