        src/sys/dev/mii: mii_physubr.c

Log Message:
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.
