- 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.

The chip design is crazy -- on RX, it puts the 16-bit VLAN tag

aue_tick calls several synchronous usb functions from a timeout(9),
this is very broken since a timeout(9) is run as an interrupt
and the usb functions tsleep.
A stopgap fix is to schedule a taskqueue task from the timeout
and defer work to that taskqueue task.
Preliminary support for Atmel AT45D series of DataFlash on the
SPI bus (ok, not really a hardware bus, but a logical
connection). This works only for the 8MB version of the part
due to hard coding. Both read and write are supported.

- Implement a separate nsphy_reset(). There are two reasons for this:
1) This PHY can take an inordinate amount of time to reset if media
is attached; under fairly normal circumstances up to nearly one
second. This is because it appears to go through an implicit auto-
negotiation cycle as part of the reset.
2) During reset and auto-negotiation, the BMCR will clear the reset
bit before the process is complete. It will return 0 until the
process is complete and it's safe to access the PHY again.
This is the first of two changes required to make the combination of
Am79c971 and DP83840A found on certain HP cards and on-board in IBM

an URQ_REQUEST when DMA segments are passed to usbd_start_transfer();
when the request doesn't include the optional data buffer the size of
the transfer (xfer->length) is 0, in which case usbd_transfer() won't
create a DMA map but call usbd_start_transfer() with no DMA segments.
With the previous change this could result in the bus_dmamap_sync()
implementation dereferencing the NULL-pointer passed as the DMA map
argument.
While at it fix what appears to be a typo in usbd_start_transfer();
in order to determine wheter usbd_start_transfer() was called with
DMA segments check whether the number of segments is > 0 rather than
the pointer to them being > 0.
