- Use more consistent and portable types in the softc.
- Map registers using an array of bus_size_t offsets, and set up the
mapping in the attach code (thanks to Jason Thorpe for suggesting
this!).
- Disable the ae-specific watchdog, which is no longer necessary in
the general case.
Still remaining: split out functions used to copy data to/from the
card, and retain a way to have a local driver name with the MI code.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
determine whether there was an error (if so, we unmap the slot space
for this device). Use this functionality to tell the attach function
that we couldn't clear the card's buffer.
Also in aesetup(), eliminate the bogus repetition of the error message
we print when the buffer clear actually fails. Noticed by Hauke Fath.
and allow the attach function to override the default watchdog. Also,
do some minor cosmetic surgery (rename bus space tags/handles and some
KNFing I missed the first time around).
