Log:
Rework the support for the internal autonegotiation on the 21143 and
workalike chips (Macronix 98713A/98715 and PNIC II). Timing is somewhat
critical: you need to bring the link as soon as possible after NWAY
is done, and the old one second polling interval was too long. Now
we poll every 10th of a second until NWAY completes (at which point
we return to the 1 second interval again to keep an eye on the link
state).
I tested all the other cards I had on hand to make sure I didn't bust
any of them and they seem to work (including the MII-based 21143 card).
This should fix some autoneg problems with DE500-BA cards and the
built-in 10/100 ethernet on some alpha systems.
(Now before anyone asks why I never noticed this before, the old code
worked just find with the Intel swich I used for testing back in NY.
Apparently not all switches are as picky about the timing.)
