MFC will occur in due time and probably in stages.
BUGFIX: fix a problem in old code which prevented reallocation of
the hash table for dynamic rules (there is a PR on this).
OTHER CHANGES: minor changes to the internal struct for static and dynamic rules.
Requires rebuild of ipfw binary.
Add comments to show how data structures are linked together.
(It probably makes no sense to keep the chain pointers separate
from actual rule descriptors. They will be hopefully merged soon.
keep a (sysctl-readable) counter for the number of static rules,
to speed up IP_FW_GET operations
initial support for a "grace time" for expired connections, so we
can set timeouts for closing connections to much shorter times.
merge zero_entry() and resetlog_entry(), they use basically the
same code.
clean up and reduce replication of code for removing rules,
both for readability and code size.
introduce a separate lifetime for dynamic UDP rules.
fix a problem in old code which prevented reallocation of

introduce some local variables to avoid multiple dereferencing of

seems to set up memory spaces correctly. This change actually did work for
me using -STABLE, XFree86 4.0.3 ~ some snapshot of DRI awhile back. I sent
mail to dfr to no avail, perhaps someone else would like to test it with
DRI.
Anyway, people have been nagging me about this change for awhile, so here's
the commit.

Also increase the size of the RX ring to 128 descriptors (was 64).

generally speaking, there are few instances of this, and they should
be fixed.

Please note, that due to limit on the amount of memory available to the
loader(8), it is possible to load modules/kernels compressed with the smallest
block size supported by the bzip2 - 100k (`-1' bzip2(1) option), however
even in this mode bzip2(1) usually provides better compression ratio than
gzip(1) in its best compression mode.

This works if /dev exists, or if / is read/write (nfsroot). If it is
too hard, leave it up to init -d (which will probably fail if /dev does
not exist, but there isn't much else we can do short of making a union
mount on /).
This means we get a proper /dev if you boot a 5.x kernel on a 4.x world,
which I happen to do often (the ramdisks on our install netboot servers
have 4.x userland worlds on them).

The "card" identifier string is assigned to a logical device as the

identifier string has not been found, use the EISA PnP ID string.
Strictly speaking, this is an error.) We will override it when a

Minor overhaul of how we do interrupts for the pci interrupt routing
case to cope with card ejection better (read: make it not hand on so
many cards):
o Reintroduce func_intr and func_arg and use the to store the
interrupt handler to call.
o Create a pcic_pci_func_intr to call the real interrupt handler
iff the card hasn't been ejected.
o Remove some checks in pcic_setup_intr now that it is used
exclusively for isa routed interrupts.
o Defer the eject event until later too, but make sure we can't
do any client driver ISR calling in the interrum.
o Add some simple code to make sure that we don't attach more
than one child. This should fix pccardd starting twice
problem (ala single user -> multi-user when you started pccardd
by hand in SU).
