This chip makes it hard to do proper auto, so we don't do it. We

o When forced to be 10baseT, don't require that the 10baseT interface
have link to succeed. Still require it for IFM_AUTO, however, since it
appears that there's no way to tell if a specific type of interface
worked. I'm doing a web search for a datasheet now to see if there's
anything obvious.
o Minor incidental formatting nits, including collapsing code of the form

similar to if_timer and reset the chip if it gets down to zero via the
decrement.
- Use IFQ_SET_MAXLEN().
The Giant lock is acquired in two places in tty_tty.c. In both places,
it is unneeded.
There is no reason to specify D_NEEDGIANT on this device node. The
device node has only been designed to return ENXIO when opened. It
doesn't make any sense to lock/unlock Giant, just to return this error.
D_TTY is also unneeded. The unimplemented functions don't need to be
patched by devfs.
We don't need to lock Giant when we want to lookup the proper TTY vnode.
s_ttyvp is already protected by proctree_lock (see devfs_vnops.c).

bring it more up to date. The watchdog timer, and its
associated code, is all collapsed into the ndis_tick function
that was implemented for the NDIS-subsystem watchdog. This
implementation is similar to what numerous other drivers use
to implement the watchdog.

- Add a mutex to the softc and use it to protect the softc and device.
- Setup the interrupt handler in the common code instead of in each front
end and do it after ether_ifattach().
- Use ie_stop() and ieinit_locked() in iereset() rather than frobbing IFF_UP
and invoking ieioctl().
- Use DELAY() to implement a spin loop on a register with a timeout rather
than scheduling a timeout and then doing a tight spin on the register.
In the non-MPSAFE case this would never have worked because the spinning
code held Giant and the timeout routine would have been blocked on Giant
forever. The same approach would not worke in the MPSAFE case either for
the same reason, hence use a loop around DELAY().
- Clear IFF_DRV_(RUNNING|OACTIVE) in ie_stop() rather than in callers.
- Call ieinit_locked() directly rather than ieioctl(!) from ie_mc_reset().
- Don't leak the rx frame buffer on detach.

In the mpsafetty branch, Linux sshd seems to work properly inside a
jail. Some small modifications had to be made to the Linux compatibility
layer.
The Linux PTY routines always expect the device major number to be 136
or higher. Our code always set the major/minor number pair to 136:0.
This makes routines like ttyname() and ptsname() fail, because we'll end
up having ambiguous device numbers.
The conversion was not performed on all *stat() routines, which meant in
some cases the numbers didn't get transformed. By pushing the conversion
into linux_driver_get_major_minor(), the transformation will take place
on all calls.
