o Remove unused static global variable e1000phy_debug.
o Take advantage of mii_phy_dev_probe().
o Use MII_ANEGTICKS/MII_ANEGTICKS_GIGE instead of magic number 5.
o Add IFM_NONE as e1000phy(4) supports it without issues.
o Nuke magic PHY programming sequence in PHY reset and follow correct
reset sequence. [1]
o Make manual media selection work for all supported media types.
o Don't set MIIF_NOISOLATE so e1000phy(4) can be used in
configurations with multiple PHYs.
o In 1000baseT, when setting the link manually, one side must be the
master and the other the slave. If LINK0 is set, program the PHY
to be a master, otherwise it's a slave.
o When we lost a link, reset mii_ticks immediately so it correctly
check number of seconds elapsed in autonegotiation phase.
o Announce link loss right after it happens.
o After kicking autonegotiation, report PHY status instead of
returning immediatly.
o When link state check is in progress, check auto negotiation
completion bit only when auto negotiation is enbaled.
o When PHY is resolved to a master, show it with IFM_FLAG2.
Special thanks to marius who fixed several nits in original patch.
In half-duplex mode, nfe(4) fails to send packets. I think it's a bug
in nfe(4) as the same PHY works without problems on msk(4).

Either they're there early and the ispfw sets have
registered themselves, or they're not.
The module dependency stuff isn't quite what we want
anyway. If the user doesn't want the load placed on
system memory by loading the firmware, they don't
specify it to be loaded (either by being linked in
or via being a module to be loaded and then hooked
in with firmware(9)). It doesn't then make sense to
then override what they want by pulling it in anyway.
This might be able to work if we were able to pull in
just exactly what we needed for the card we have- but
that's an optimization left for the future.

with- not hope for the best. Change some things which were gated
off of 24XX to be gated off of 2K login support. Convert some
isp_prt calls to xpt_print calls.
Add a note that suggests a cleanup.
Note: This patch was derived based on looking at the pvrxxx/pvr250
ports' Makefiles only, and may be incomplete. It is not derived from
anything I saw from Hauppage.
- In hme_eint() print MIF register contents on MIF interrupts.
- In hme_mifinit() don't bother to preserve the previous MIF config.
This was mainly done in order to preserve the PHY select bit (external
or internal PHY) but which only needs to be set as appropriate when
reading from or writing to the desired PHY in hme_mii_{read,write}reg().
Similarly don't bother to set the PHY select bit in hme_mii_statchg().
- In hme_mii_{read,write}reg() ignore requests to PHYs other than the
external and internal PHY one.
- Move enabling/disabling the MII drivers of the external transceiver
from hme_init_locked() and based on the sheer presence of an external
to hme_mifinit() and based on the currently selected media, defaulting
to the internal transceiver when the media hasn't been set, yet.
Invoke hme_mifinit() from the newly added hme_mediachange_locked() so
the setting of the MII drivers is updated when changing media.
These changes keep the MII bus from wedging (which manifests in the HME
and the PHYs no longer being able to communicate with each other) when
the PHY device drivers isolate the unused PHY in two-PHY configurations
as present in f.e. Netra t1 100 while changing media, either from
hme_init_locked() (see also below) or via ifconfig(8). They also allow
for using both transceivers/PHYs.
- In the newly added hme_mediachange_locked() also reset the PHYs in two-
PHY configurations before invoking mii_mediachg(). This is required
for successfully unisolating the previously unused PHY when switching
between PHYs.
- Now that changing media should no longer cause problems back out rev.
1.27 and re-enable setting the current media in hme_init_locked() (see
the commit message of rev. 1.23 for more info).
These changes are roughly a merge of NetBSD gem.c rev. 1.32 - 1.35 (1.30
was already fixed differently in our 1.36; 1.31 and 1.32 were wrong) with
some parts reworked and things that don't make sense like setting the MII
drivers and restoring the previous MIF and XIF settings in hme_mii_{read,
write}reg() omitted.

read wasn't flagging the SYNC mode was enabled. The temp
values for offset and sync period were uint8_t, but were
being assigned and shifted from a uint32_t value.
This didn't show up in testing because a random number
of 1030 cards set a bit that says "honor BIOS negotiation",
which means this whole code path was skipped.
This should clear up at least some of the negotation
issues that have been seen.
Fix things to use the LSI-Logic Fusion Library mask and shift names for
offset and sync, no matter how awkward they are, in preference to just
plain numbers.
- Don't set MIIF_NOISOLATE so amphy(4) can be used in configurations
with multiple PHYs. There doesn't seem to be a problem with isolating
AM79c873 and workalikes per se nor in combination with the NICs they're
used with and amphy(4) was already adding IFM_NONE anyway.
- Use mii_phy_add_media() instead of mii_add_media() so the latter can
be eventually retired.
