ce2ec9e63e Add support for the SMsC LAN83C183 PHY, which actually probes as a 
Seeq 84220.

Also add an 84220-specific work-around for some braindamage (at least
in the PHY I'm working with) where the PHY always comes out of reset
isolated, regardless of the previous state of the BMCR_ISO bit. This
happens even if the PHY has address zero, which is contrary to the
part's datasheet...

The work-around is only applied if we notice BMCR_ISO is set when it
should be clear following reset. The fix is to wait 30mS and clear
it manually. (The change doesn't stick if it's cleared sooner than this)

c19a094675 Don't include <malloc.h> - no memory management style functions are use 
in any of the MII drivers.

b017898534 Get flags passed down to PHY drivers correctly. This was done on 
an adhoc basis in a couple of PHY drivers, this fixes it more generally.

Per a discussion w/ Cliff Neighbors <cliff@allegronetworks.com>.

7914a89b02 Add support for the Seeq 80225 10/100 Ethernet PHY. This is just 
a stripped-down version of the 80220/80223.

ea1aed7db2 Make the number of ticks between auto-negotiation tries PHY-specific, 
and default every PHY to 5 seconds (what we used before).  If we find
Gig-E media on a PHY, bump it to 10 seconds, since it can take 5
seconds just to negotiate a Gig-E link.

49014bf59f Restructure the PHY entry points to use a structure of entry points 
instead of discrete function pointers, and extend this to include
a "reset" entry point.  Make sure any PHY-specific reset routine is
always used, and provide one for the LXT-970 which disables MII
interrupts (as is done for a few other PHYs we have drivers for).

8923ca0b00 Make PHY drivers provide a pointer to their status routine, and add 
a generic mii_phy_status() that calls back into the PHY.  It doesn't
do anything interesting yet, but it will soon.

eed75dbc26 Don't dry to diving MIIF_NOISOLATE in the PHY drivers. Instead, pass 
flags down from the parent to child vi mii_attach().

bca88a28c8 Add mii_down(), which is used by MAC drivers to inform PHYs that the 
interface is now down.  PHYs use this to cancel pending asynchronous
operations.

83f9ab3c87 Implement asynchronous autonegotiation when driven by the MII tick 
(one-second clock).  Prevents .5s delays every 5 seconds when the interface
is up but there is no link.  Fixes PR 7361.

aabf2a0809 In the status routine, always use the media selected in the BMCR if 
autonegotiation is not enabled.  This is more reliable on many PHYs,
and requires fewer register reads.

2a17544c19 Place the essentially common "ticks" and "active" members into the 
mii_softc (generic phy goo), and just switch all of the PHY drivers
(except tlphy, which really does have special stuff) to use an mii_softc
instead of a private one.

ad8b66c7c8 Return a higher-priority match than 1. These are specific drivers. This 
allows for a "generic unknown PHY" driver to be implemented.

51da8fc39f Factor out the common reset code. Use the NOISOLATE flags as appropriate 
to prevent a PHY from being isolated in the event the MAC can't deal with
this.  (3Com 3c905B-TX, and Intel i82557).
