Modified Files:
        src/sys/dev/mii: nsphy.c

Log Message:
Implement a separate nsphy_reset().  There are two reasons for this:

        1) This PHY can take an inordinate amount of time to reset if
           media is attached.  Under fairly normal circumstances, up
           to near one second.  This is because it appears to go through
           an implicit autonegotiation cycle as part of the reset.

        2) During reset and autonegotiation, the BMCR will clear the reset
           bit before the process is complete.  It will return 0 until the
           process is complete and it's safe to access the PHY again.

This gets the on-board pcnet + nsphy ethernet working properly for me on
an IBM PC Server/325.  Fixes PR/16346.
