probing the novell ne[12]000 cards. It should be its own thing, ala
how we do the dl100xx support doing its own thing at the right time.
For the moment, it is just a function, which makes the mainline of the
generic probe easier to follow.
Also, correct a couple of comments that looked wrong.
# there may be a bug in setting up gwether, in that we set
# sc->rec_page_stop based on memsize, rather than sc->mem_size, so if
# these two are different, then the rec_page_stop will be wrong. I'm
# hesitant to fix it without real hardware to test with. Since
# gwether isn't in the hardware list of the man page nor in the commit
# messages, it is hard to know for sure.
invalidate pending io and dependencies. However, vinvalbuf() rightfully
does not call vnode_pager_setsize() for us. We must do this here. This
could potentially have caused numerous kinds of bugs, but it was
specifically causing msync() deadlocks because msync() was writing
flushing pages that should not have been valid.

and wd80x3 support. Make the obscure ISA cards optional, and add
those options to NOTES on i386 (note: the ifdef around the whole code
is for module building). Tweak pc98 ed support to include wd80x3 too.
Add goo for alpha too.
The affected cards are the 3Com 3C503, HP LAN+ and SIC (whatever that
is). I couldn't find any of these for sale on ebay, so they are
untested. If you have one of these cards, and send it to me, I'll
ensure that you have no future problems with it...
Minor cleanups as well by using functions rather than cut and paste
code for some probing operations (where the function call overhead is
lost in the noise).
Remove use of kvtop, since they aren't required anymore. This driver
needs to get its memory mapped act together, however, and use bus
space. It doesn't right now.
This reduces the size of if_ed.ko from about 51k to 33k on my laptop.
parantheses. This helps editors to find its way through the horrible
mess of Var_Parse. Rewrite a for() loop into a while() to make it clearer.

nodes from (N + 1) to 1, where N is the number of
nodes in the system.
- Implement "ls -l" which runs the "show" command for
each node.
In collaboration with: glebius
The difference is that the callout function installed via the
ng_callout() method is guaranteed to NOT fire after the shutdown
method was run (when a node is marked NGF_INVALID). Also, the
shutdown method and the callout function are guaranteed to NOT
run at the same time, as both require the writer lock. Thus
we can safely ignore a zero return value from ng_uncallout()
(callout_stop()) in shutdown methods, and go on with freeing
the node.
The said revision broke the node shutdown -- ng_bridge_timeout()
is no longer fired after ng_bridge_shutdown() was run, resulting
in a memory leak, dead nodes, and inability to unload the module.
Fix this by cancelling the callout on shutdown, and moving part
responsible for freeing a node resources from ng_bridge_timer()
to ng_bridge_shutdown().

Giant held. In camisr(), move the ccb_bioq elements to a temporary local list
and then process the elements off of that list. This enables the list to be
processed by only taking the ccb_bioq_lock once and only for a very short
time.
ccb_bioq_lock is a leaf mutex, so it's fine to call xpt_done() with other
locks held. This is just a very minor step in the work to lock CAM, but
it allows us to avoid some messy locking/unlock dances in certain drivers.
4 mutex operations per I/O requests.
- Use only one mutex to protect both (incoming and outgoing) queue.
As MUTEX_PROFILING(9) shows, there is no big contention for this lock.
- Protect sc_queue_count with queue mutex, instead of doing atomic
operations on it.
- Remove DROP_GIANT()/PICKUP_GIANT() - ggate is marked as MPSAFE and no
Giant there.
same as the LINKSYS COMBO_ECARD (which also seems to be the same as
another linksys product that also has a modem, but I can't find that
one at the moment). Remove the PCM100, since it is now no longer
used.
o The COMBO_ECARD comes in many flavors, it seems, so probe both the DL10019
and the AX88x90 on it. Since this seems to work with no ill effects, maybe
the probing should happen more generally rather than being table driven.
Need to think more about this.
o Remove PCM100 because it is duplicative (the ETHERFAST is the pcm100 and
apparently has the same IDs). It was here for NetBSD because they match
up an expected MAC address OID, but since we don't bother with that, we
don't need to be so finely discriminating.
o Minor style nit.
if_ed_isa.c, and they seem to not be helpful anymore.
o Fix style issues from de-Pification.
o change from _isa_ to _cbus_ to the largest extent possible to reflect that
this is really for cbus, not isa.
o Use ANSI function definitions.
o Use ed_clear_memory
o eliminate kvtop
