patch workarounds for each phy revision.
Obtained from: NetBSD & Broadcom Linux driver
- Disable AUTOPOLL when accessing the PHY as it may cause PCI errors.
Obtained from: NetBSD
- Check the UPDATED bit in the status block so the driver knows
that the status block as indeed changed since the last access.
Broadcom documentation states drivers should unset the UPDATED/CHANGED
bits after reading them.
- When changing media types, first loop the phy then set the media.
Broadcom documentation and Linux drivers do this and I observed
much better handling of link after this change.
- Broadcom documentation states that for 1000BaseT operation,
autonegotiation must be enabled. Fix hard coding of media so that
the driver only advertises 1000BaseT as the supported media type
and enable autonegotition.
- Only set Master/Slave on the 5701.
Obtained from Broadcom Linux driver.
cards to test; however the submitter reports that this patch works
with the on-board interface on the IBM x235 server.

Rename mii_phy_auto_stop() mii_phy_down().
Introduce mii_down(), use it from nge. Do not indirect it to 19 identical
case's in 19 switchstatements like NetBSD did.
. Make internal service routines static.
. Use a consistent ordering of checks in MII_TICK. Do the work in the
mii_phy_tick() subroutine if appropriate.
. Call mii_phy_update() to trigger the callbacks.
