This makes it possible for HW PHY-less boards to utilize PAL goodies. Generic
routines to connect to fixed PHY are provided, as well as ability to specify
software callback that fills up link, speed, etc. information into PHY
descriptor (the latter feature not tested so far).

Prevent phylib from freeing PHY IRQ twice on closing an eth device:
phy_disconnect() first calls phy_stop_interrupts(), then it calls
phy_stop_machine() which in turn calls phy_stop_interrupts() making the
kernel complain on each bootup...

The phy ids used are taken from an driver that used a right shift of 4 to chop
off the revision number. This driver does not shift, so the id and mask
values are wrong and must be left shifted by 4 to actually detect the chips.

Andy,
libphy has no license tag. Something like the attached (untested!) patch
is needed. Hopefully such a change finds its way into 2.6.15.

Adds a phy_mask field to struct mii_bus and uses it. This field
indicates each phy address to be ignored when probing the mdio bus.
This support is needed for the fs_enet and ibm_emac drivers to be
converted to the generic phy layer among other drivers. Many systems
lock up on probing certain phy addresses or probing doesn't return
0xffff when nothing is found at the address. A new driver I'm
working on also makes use of this mask.

In PM v1, all devices were called at SUSPEND_DISABLE level. Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level. However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.

When building with CONFIG_PHYLIB=y on Itanium, I see:
`mdio_bus_exit' referenced in section `.init.text' of
drivers/built-in.o: defined in discarded section `.exit.text' of
drivers/built-in.o
I believe that mdio_bus_exit should not be declared __exit, because it is
referencesd from __init sections in, say, phy_init().

This patch adds back the code that was taken out, thus re-enabling:
* The PHY Layer to initialize without crashing
* Drivers to actually connect to PHYs
* The entire PHY Control Layer
This patch is used by the gianfar driver, and other drivers which are in
development.
