Add media types and options for ATM. While on most ATM cards media cannot
be changed, it is very convenient to be able to toggle SDH/Sonet,
idle/unassigned cells and scrambled mode and to see the carrier
state.
Revamp the newbus functions:
o do not use the in* and out* functions. These functions are used by
legacy drivers and thus must have ia32 compatible behaviour. Hence,
they need to have fences. Using these functions for newbus would
then pessimize performance.
o remove the conditional compilation of PIO and/or MEMIO support. It's
a PITA without having any significant benefit. We always support them
both. Since there are no I/O ports on ia64 (they are simulated by the
chipset by translating memory mapped I/O to predefined uncacheable
memory regions) the only difference between PIO and MEMIO is in the
address calculation. There should be enough ILP that can be exploited
here that making these computations compile-time conditional is not
worth it. We now also don't use the read* and write* functions.
o Add the missing *_8 variants. They were missing, although not missed.
It's for completeness.
o Do not add the fences that were present in the low-level support
functions here. We're using uncacheable memory, which means that
accesses are in program order. Change the barrier implementation
to not only do a memory fence, but also an acceptance fence. This
should more reliably synchronize drivers with the hardware. The
memory fence enforces ordering, but does not imply visibility (ie
the access does not necessarily have happened). This is what the
acceptance deals with.
cpufunc.h cleanup:
o Remove the low-level memory mapped I/O support functions. They are
not used. Keep the low-level I/O port access functions for legacy
drivers and add fences to ensure ia32 compatibility.
o Remove the syscons specific functions now that we have moved the
proper definitions where they belong.
o Replace the ia64_port_address() and ia64_memory_address() functions
with macros. There's a bigger change inline functions get inlined
when there aren't function callsi and the calculations are simply
enough to do it with macros.
Replace the one reference to ia64_memory address in mp_machdep.c to
use the macro.
Add module data and version to the atm_subr and reference this info from the
(currently) only consumer (en).
Add a sysctl node hw.atm where the atm drivers will hook on their hardware
sysctl sub-trees.
Make atm_ifattach call if_attach and remove the corresponding call to if_attach
from en. Create atm_ifdetach and use that in en.
While the last change actually changes the interface this is not a problem in
practice because the only other consumer of this API is an older LANAI driver
on the net, that is not ready for current anyway.
Keep syscons specific I/O functions internal/specific to syscons on
ia64 by defining them in terms of newbus. Add a static inline for
fillw(), which doesn't have anything to do with I/O.
It's still ugly, but now the ugliness can be removed from ia64
specific headers.

Fix 5 bugs:
1) always call fxp_stop in fxp_detach. Since we don't read from
the card, there's no need to carefully look at things with
bus_child_present.
2) Call FXP_UNLOCK() before calling bus_teardown_intr to avoid
a possible deadlock reported by jhb.
3) add gone to the softc. Set it to true in detach.
4) Return immediately if gone is true in fxp_ioctl
5) Return immediately if gone is true in fxp_intr

Don't hold a driver lock across bus_teardown_intr. Jhb points out
that one cannot generally hold a lock and call bus_teardown_intr.
This is race free with wi_intr because bus_teardown_intr won't allow
wi_intr to be called after it returns.
# jeff hsu points out that there might be a race between this unlock
# and wi_start. While that may be true also, it won't impact this commit.

Make 2/3 of my symbol cards work again. The 3rd symbol card card has
firmware 1.50.12, but 2.20.1 and 3.10.4 work. The 1.50.12 card gets
past doing dhclient, but hangs on transmit a little after the ip
address is set. The 1.50.12 card has always been 'cranky' and Bill
Paul's tearing it apart at FreeBSD '99 hasn't helped.
sc_reset and sc_enable are subtlely different things. sc_reset means
exactly "WI_CMD_INI has happened." sc_enabled means "WI_CMD_ENABLE
has been sent to the card without a WI_CMD_DISABLE following." This
is a little different than what they mean on NetBSD (where both of
these concepts are comingled). NetBSD will try to only enable symbol
cards once, while FreeBSD only sends the WI_CMD_INI once.
Also, only try once to reset the card on a symbol.
This makes the lucent cards no worse than before, but apparently not
much better either. I got fewer hangs in my testing than I have in
the past, but I don't know if it is statistically significant or not.
