and check device_is_active() there. Make the mii_*() routines call
the PHY service routines thorugh phy_service() instead of PHY_SERVICE().
In mii_phy_resume(), restore a PHY's state after resetting it by
sending a MII_MEDIACHG command. This change makes bnx(4) resume
more reliably and more quickly; it should help other NICs to resume,
too, if they attach PHYs through MII.
This makes autonegotiation on rlphy(4) at re(4)

bus-independent backend, with PCI and CardBus attachment code.
The committed code has two serious bugs:
1. The driver makes no attempt to recover resources when a (Cardbus)
instance is removed; bus resources are leaked.
2. In testing with a NetGear GA-511, the Cardbus card never responded
to a reset/wakeup if the card is powered down after attachment.
So for now, leave cardbus instances powered up at attachment
(insertion, or at boot if a card is already present).
That aside, it acutally works on my GA-511. Committed as-is despite
the bugs, after repeated requests to make the code available for
further testing. Also requires sys/dev/mii/miidevs rev 1.54 -> 1.55,
and consequent regen of miidevs{,_data}.h.

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.
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.
