74495bcdab Revert change to detect multiply PHYs in mii code. There might be cases
when this is needed.  Work around bogus second PHY in the DFE-580 card
via a change in the if_ste.c driver.

130be1f120 Only attach one PHY device to a controller. NetBSD has similar code.
The D-Link DFE-580 card will otherwise show 2 miibuses for each controller
and therefore 2 ukphy's.

d82bc4fba8 Add a driver for the Broadcom BCM52xx "mini-theta" PHY. This includes the
internal PHY on the 3COM 3C905B and 3C905C parts, however I've rigged it so
that xlphy (aka exphy) takes precedence for the time being.

If people try this with their xl cards and decide that it's a better choice,
we can switch this later.

This is the PHY used in various iMacs and possibly other GMAC-equipped
Macintoshes with 10/100 PHYs (the ones with 10/100/1000 appear to use brgphy).

daec3648eb Use 3C905C instead of 3c905Cphy as the identifier for the Broadcom PHY used
in the 3C905C.  This is mainly cosmetic.

I'm doing this mainly so we share the same identifier as NetBSD.

4592db4635 MII_TICK handlers need not restart aneg on these PHYs, they behave pretty
well as is, so - just fetch current status upon MII_TICK.

Also do IFM_INST verification at the top of *_service() then doing it
separately for every case in switch.

acphy: do not read MII_ACPHY_DIAG twice, there is nothing latching.
qsphy: always fetch actual link status from MII_QSPHY_PCTL.

e3c5a44915 Work around an Intel 21143 chip bug.
Rev 1.56 of if_dc.c removed calls to mii_pollstat() from the dc_tick()
routine.  dc_tick() is called regularly to detect link up and link down
status, especially when autonegotiating.

The expectation was that mii_tick() (which is still called from dc_tick())
would update status information automatically in all cases where it would
be sensible to do so.

Unfortunately, with authentic 21143 chips this is not the case, and
the driver never successfully autonegotiates.  This is because (despite
what it says in the 21143 manual) the chip always claims that link is not
present while the autonegotiation enable bit is set.  Autonegotation takes
place and succeeds, but the driver tests the link bits before it switches
off the autonegotiation enable bit, and success is not recognised.

The simplest solution is to call dcphy_status() more often for MII_TICK
calls by dropping out of the switch statement instead of exiting when
we are autonegotiating and link appears to not be present.  When
autonegotiation succeeds, dcphy_status() will note the speed and fdx/hdx
state and turn off the autonegotiation enable bit.  The next call to
dcphy_status() will notice that link is present, and the dc driver code
will be notified.

Macronix chips also use this code, but implement link detection as
described in the manual, and hence don't need this patch.  However, tests
on a Macronix 98715AEC-C show that it does not adversely affect them.

This could be done better but is the minimal effective change, and most
closely mimics what was happening prior to rev 1.56 of if_dc.c.  (Actually
I also deleted a small amount of unnecessary code while I was in the area.)

a72c060fb0 Teach the rlphy driver how to do parallel link detection. If the link partner
doesn't support NWAY, the RealTek PHY (both the integrated ones on 8139
chips and the RTL8201L 10/100 PHY) will not report the link speed via
the ANLPAR or BMSR registers. For the 8201L, we need to look in magic
vendor-specific PHY register 0x19. For the 8139 MAC+PHY combo, we have
to be able to test the RL_MEDIASTAT register.

The changes to rlphy.c are based largely on the patch from PR 30836,
however I tried to eliminate some magic numbers by creating an entry
for the 8201 PHY in miidevs.

Also updated if_rl.c to allow the rlphy driver to read the RL_MEDIASTAT
register via the rl_miibus_readreg() routine.

e46e7fa2c2 Only touch the PCR register in order to set bits for the fxp driver.
The 3C509-TX card apparently had a slightly different version of the
chip, and has problems when this register is set.  The problem does
not appear on the 3C509{BC} cards, but since only the fxp driver needs
specific bits set, conditionalize on that.

134c58d3c0 Tweak the xmphy driver a little bit based on something I learned about
the built-in 1000baseX interface in the Level 1 LXT1001 chip. The Level 1
PHY comes up with the isolate bit in the control register set by default,
but it also has the autonegotiate bit set. When you tell the xmphy driver
to select IFM_AUTO mode, it sees that the autoneg bit is already on, and
thus doesn't bother updating the control register. However this means that
the isolate bit is never turned off (unless you manually select 1000baseSX
full or half duplex mode, which does result in the control register being
modified and the ISO bit being turned off).

This subtle and unusual behavioral difference stopped me from being able
to receive packets on the SMC9462TX card for several days, since isolating
the PHY disconnects it from the MAC's data interface. The fix is to omit
the 'is the autoneg big set?' test, since it doesn't really provide much
of an optimization anyway.

This commit also updates the xmphy driver to support the Jato/Level 1
internal PHY. (I'm not sure how Jato Technologies is related to Level 1:
all I know is the OUI from the PHY ID registers maps to Jato in the OUI
database.) This will be used once I add the if_lge driver to support
the LXT10010 chip.

ce4946daa5 Add support for gigabit ethernet cards based on the NatSemi DP83820
and DP83821 gigabit ethernet MAC chips and the NatSemi DP83861 10/100/1000
copper PHY. There are a whole bunch of very low cost cards available with
this chipset selling for $150USD or less. This includes the SMC9462TX,
D-Link DGE-500T, Asante GigaNIX 1000TA and 1000TPC, and a couple cards
from Addtron.

This chip supports TCP/IP checksum offload, VLAN tagging/insertion.
2048-bit multicast filter, jumbograms and has 8K TX and 32K RX FIFOs.
I have not done serious performance testing with this driver. I know
it works, and I want it under CVS control so I can keep tabs on it.
Note that there's no serious mutex stuff in here yet either: I need
to talk more with jhb to figure out the right way to do this. That
said, I don't think there will be any problems.

This driver should also work on the alpha. It's not turned on in
GENERIC.
