2bf52b991f Remove mii_media_from_bmcr(); all previous users have been converted to
use mii_phy_add_media()/mii_phy_setmedia().

a35b933378 Add a helper function mii_phy_dev_probe(), which wraps around the
mii_phy_match() API and takes care of the PHY device probe based on
the struct mii_phydesc array and the match return value provided.
Convert PHY drivers to take advantage of mii_phy_dev_probe(),
converting drivers to provide a mii_phydesc table in the first
place where necessary.

9475e904d6 Analogous to mii_add_media(), factor out the code for checking whether
the BMSR contains any media at all to mii_phy_add_media(). The majority
of the drivers currently using mii_phy_add_media() were missing such a
check anyway though.

0c3e319244 - Add a MIIF_FORCEANEG flag which forces an auto-negotiation to always
take place if IFM_AUTO is selected. This allows drivers like nsphy(4),
  which need to force writing the ANAR according to the BMSR, to take
  advantage of mii_phy_setmedia(). [1]
- In mii_phy_reset() once the current media is set don't isolate the PHY
  corresponding to the instance of the currently selected media rather
  than unconditionally not isolating the PHY corresponding to instance 0.
  This saves a isolation-unisolation-cycle of the PHY corresponding to
  the currently selected media for the case were it isn't instance 0.
- Fix some whitespace nits. [1]

29aea9ec7d 1) Fix mii_phy_tick():
Current code does not report link loss correctly - when link goes down,
   mii_phy_tick() will notice that with up to mii_anegticks delay.
   If link goes up during this delay then link flapping will be unnoticed
   by driver.

2) mii_phy_add_media(): initialize sc->mii_anegticks for 10/100 media

3) Use MII_ANEGTICKS/MII_ANEGTICKS_GIGE defines instead of hardcoded values.

08576af02f Add a more generic version of the mii_phy_match routine (mii_phy_match_gen)
which can be used for phy that want to piggy back other data with their
table.

9a54cbb95d Correct the phy_service() routine case MII_TICK to correctly track
the falling edge of a media state change.

This is in preparation for media state change notification to the

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

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.

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.
