This is a major reworking of the AX88x90 support.
o Introduce new chip_type AX88790. There's a few places we need to know the
exact chip for workaronds.
o Explain the AX88190 workaround for the ISR bits being stuck, and don't
apply them to the AX88790. The datasheet says the bits are fixed, and
experience confirms.
o Fix mii bit-bang read code to read and discard the 'floating' bit.
o Remove empty ed_pccard_ax88x90_mii_reset routine
o Report error from mii_phy_probe
o Don't use ed_probe_Novel_generic for ax88x90 chips. It puts them into
an odd state sometimes. Instead, use a more stream-lined version that
avoids the trouble spots. This was copied and tweaked from the original.
o Move chip reset into its own routine.
o Minor code optimiation on getting MAC address
o Add code for coping with AX88790 cards that are in power down state and
need to be kicked before the PHY registers for the internal phy read right.
o Remove ugly cap of PHYs at 17.
o For AX88790, we need to set a special bit for accessig phy 16 (the internal
phy) and clear it for all others according to a chip erratum.
o streamline the bit-bang code for AX88x90: the delays aren't needed according
to the datasheet timing diagrams and also the Linux driver
o Fix minor bit definition for direction bit.
o Generally: Some comments reformatted
o Only try the toshiba probe on cards labelled as toshiba
# From another Akihabara card (this one from a few years ago from a
# friend in Japan). Fix the Corega FEther II PCC-TXD. This one is
# still on sale new, as of a few weeks ago. should fix all other AX88x90
# based cards, but I have some testing left to finish on my collection...
