9fe2378664 For HomePNA PHYs, don't register it w/ ifmedia as 10BASE-T, but 
rather as HomePNA1.

7459c35d44 Clean up 1000BASE-SX autonegotiation, and add a way to advertise 
PAUSE capability.

4a416b823f Fix 1000BASE-X duplex negotiation. That'll teach me to read the 
manual more carefully next time.

2128d9199a Enable frobbing the 1000baseT control register on Gig-E PHYs, 
used for hard-wiring master mode, and for advertising the 1000baseT
media options during autonegotiation.

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.

d3a64bd0d8 Add code to recognize and set media on GMII (Gigabit MII) PHYs. 
802.3 doens't specify ANAR or ANLPAR bits for GMII.  Need to
use PHY-specific registers for this, for now, which means we
need specific drivers for the Gigabit-capable PHYs (I think the
most common is the BCM5400).

bf2dcec4f5 Remove the use of splimp() from the NetBSD kernel. splnet() 
and only splnet() is allowed for the protection of data structures
used by network devices.

205b10ed17 Add a flag to mii_flags which will cause autonegotiation to use tsleep() 
instead of callout.  This way adapters which need a process context for
PHY register access (e.g. USB adapters) have a chance.

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).

fc96443d15 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

411a31adb2 - Go to splimp() when sending the rtsock message regarding link status. 
- Would like to notify protocols if a link goes up or down, to e.g.
  restart Duplicate Address Detection, etc.  Add a comment to this
  effect.

ad61d101be Factor out the tick handling code into a common function, and send 
rt_ifmsg's when the link speed or link status changes.

a084fd2f81 Some PHYs go off into left field for a few seconds if you attempt to kick 
autonegotiation while it's already enabled.

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.

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.

f04cb4036f move common support functions for phy drivers from mii.c to mii_physubr.c, 
so that they are not includes if no PHY is configured
(avoids code bloat if an interface driver has the "mii" attribute but
mii is not used by the particular version)

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.

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).
