all of the interface between the driver and the bus. This will enable
us to stop special casing eisa bus attachments in modules and treat them
like we treat all other busses.
In the longer run, we need to eliminate much (all?) of these interfaces
and switch to using the standard bus_alloc_resource(), but that's not
done right now.
# I've not updated the modules to include eisa, etc, just yet
Tested on: Compaq Proliant 3000/333 purchased for eisa work
mode. The 5704 apparently has some s00p3r s33kr1t registers for setting
the advertisement of pause frame ability (i.e flow control) when in
autoneg mode. If we don't set these registers correctly, we may not
be able to negotiate a proper link with some switches. (Symptom is that
the NIC reports the link as up (PCS synched) but no traffic can be
exchanged.)

Add two new functions: ttyref() and ttyrel(). ttymalloc() creates a struct
tty with a reference count of one. when ttyrel sees the count go to zero,
struct tty is freed.
Hold references for open ttys and for ttys which are controlling terminal
for sessions.
Until drivers start using ttyrel(), this commit will make no difference.
different cards that matched vendor/id, but weren't wi cards. This is
because the vendor foolishly didn't have unique product ids. Symbol
has a serial card that would otherwise match the wi driver, for
example...
Taken from a patch for xe posted by: Carlos Velasco
recursive entering of the socket code from the routing code:
- Modify rt_dispatch() to bundle up the sockaddr family, if any,
associated with a pending mbuf to dispatch to routing sockets, in
an m_tag on the mbuf.
- Allocate NETISR_ROUTE for use by routing sockets.
- Introduce rtsintrq, an ifqueue to be used by the netisr, and
introduce rts_input(), a function to unbundle the tagged sockaddr
and inject the mbuf and address into raw_input(), which previously
occurred in rt_dispatch().
- Introduce rts_init() to initialize rtsintrq, its mutex, and
register the netisr. Perform this at the same point in system
initialization as setup of the domains.
This change introduces asynchrony between the generation of a
pending routing socket message and delivery to sockets for use
by userspace. It avoids socket->routing->rtsock->socket use and
helps to avoid lock order reversals between the routing code and
socket code (in particular, raw socket control blocks), as route
locks are held over calls to rt_dispatch().

have no entries to print (either due to an empty directory or an
error). This makes the -l and -s options more consistent, like
Solaris and (Debian) Linux. To make this happen, tweak two
optimizations on the second call to display():
- Don't skip display() altogether, even if list == NULL.
- Don't skip the call to the printfn in display() if we
need to print the total.

The issue of whether this is the right errno for funopened streams is
unresolved, but that's an obscure case, and some errno is better than
no errno.

pmap_extract() already does it.
In pmap_enter(), opa has already been masked so don't do it again.
Wrap a long line (recent transgression).
Use trunc_page() in pmap_mapdev() instead of anding with PG_FRAME, since
that is what we really meant.
