Cleanup my earlier de-__P sweep and remove whitespace between function
names and paramters.

e5fbad8bca Convert exphy and ukphy over to the new code.
exphy is done flying blind, ukphy is tested on one card.

279fe8d156 Make one generic mii_phy_detach() to replace 19 slightly different ones.
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.

07dd938303 Don't pass three args when one will do just fine, and even prevent
mistakes like the one brgphy.c (now corrected).

d9730b8b53 Cleanup pass for mii drivers.
. 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.

34da0ef197 Grrrrr. That last commit was supposed to be to the head, not to -stable
(even though I want the fixes in -stable anyway). I'm sure I'm going
to get flamed now for committing to -stable and -current too quickly.
*sigh*

d00275330d This commit adds support for the NetBSD MII abstraction layer and
MII-compliant PHY drivers. Many 10/100 ethernet NICs available today
either use an MII transceiver or have built-in transceivers that can
be programmed using an MII interface. It makes sense then to separate
this support out into common code instead of duplicating it in all
of the NIC drivers. The mii code also handles all of the media
detection, selection and reporting via the ifmedia interface.

This is basically the same code from NetBSD's /sys/dev/mii, except
it's been adapted to FreeBSD's bus architecture. The advantage to this
is that it automatically allows everything to be turned into a
loadable module. There are some common functions for use in drivers
once an miibus has been attached (mii_mediachg(), mii_pollstat(),
mii_tick()) as well as individual PHY drivers. There is also a
generic driver for all PHYs that aren't handled by a specific driver.
It's possible to do this because all 10/100 PHYs implement the same
general register set in addition to their vendor-specific register
sets, so for the most part you can use one driver for pretty much
any PHY. There are a couple of oddball exceptions though, hence
the need to have specific drivers.

There are two layers: the generic "miibus" layer and the PHY driver
layer. The drivers are child devices of "miibus" and the "miibus" is
a child of a given NIC driver. The "miibus" code and the PHY drivers
can actually be compiled and kldoaded as completely separate modules
or compiled together into one module. For the moment I'm using the
latter approach since the code is relatively small.

Currently there are only three PHY drivers here: the generic driver,
the built-in 3Com XL driver and the NS DP83840 driver. I'll be adding
others later as I convert various NIC drivers to use this code.

I realize that I'm cvs adding this stuff instead of importing it
onto a separate vendor branch, but in my opinion the import approach
doesn't really offer any significant advantage: I'm going to be
maintaining this stuff and writing my own PHY drivers one way or
the other.
