Cleaner solution (e.g. adding another header) should be done here.
Original log:
Move several enums and structures required for L2 filtering from ip_fw_private.h to ip_fw.h.
Remove ipfw/ip_fw_private.h header from non-ipfw code.

This is because the switch uses iw_cm_event::status, which is an enum
iw_cm_event_status, while ECONNRESET, ETIMEDOUT and ECONNREFUSED are
just plain defines from errno.h.
It looks like there is only one use of any of the enumeration values of
iw_cm_event_status, in:
sys/contrib/rdma/rdma_iwcm.c: if (iw_event->status == IW_CM_EVENT_STATUS_ACCEPTED) {
So messing around with the enum definitions to fix the warning seems too
disruptive; the simplest fix is to cast the argument of the switch to
int.

State expire time is a baseline time ("last active") for expiry
calculations, and does _not_ denote the time when to expire. So
it should never be added to (set into the future).
Try to reconstruct it with an educated guess on state import and
just set it to the current time on state updates.
This fixes a problem on pfsync listeners where the expiry time
could be double the expected value and cause a lot more states
to linger.
forwarding a packet, that creates state, until
pfsync(4) peer acks state addition (or 10 msec
timeout passes).
This is needed for active-active CARP configurations,
which are poorly supported in FreeBSD and arguably
a good idea at all.
Unfortunately by the time of import this feature in
OpenBSD was turned on, and did not have a switch to
turn it off. This leaked to FreeBSD.
This change make it possible to turn this feature
off via ioctl() and turns it off by default.

make use of it where possible.
This primarily brings in support for newer hardware, and FreeBSD is not yet
able to support the abundance of IRQs on new hardware and many features in the
Ethernet driver.
Because of the changes to IRQs in the Simple Executive, we have to maintain our
own list of Octeon IRQs now, which probably can be pared-down and be specific
to the CIU interrupt unit soon, and when other interrupt mechanisms are added
they can maintain their own definitions.
Remove unmasking of interrupts from within the UART device now that the
function used is no longer present in the Simple Executive. The unmasking
seems to have been gratuitous as this is more properly handled by the buses
above the UART device, and seems to work on that basis.

bzero() the full compressed update struct before setting the values.
This is needed because pf_state_peer_hton() skips some fields in certain
situations which could result in garbage beeing sent to the other peer.
This seems to fix the pfsync storms seen by stephan@ and so dlg owes me
a whiskey.
I didn't see any storms, but this definitely fixes a useless memory
allocation on the receiving side, due to non zero scrub_flags field
in a pfsync_state_peer structure.
Try to make the "rtable" handling work but the current version of
pf(4) does not fully support it yet as especially callers of
PF_MISMATCHAW() are not fully FIB-aware. OpenBSD seems to have
fixed this in a later version. Prepare as much as possible.

M_NOWAIT. Currently, the code allows for sleeping in the ioctl path
to guarantee allocation. However code also handles ENOMEM gracefully, so
propagate this error back to user-space, rather than sleeping while
holding the global pf mutex.

- Define schednetisr() to swi_sched.
- In the swi handler check if there is some data prepared,
and if true, then call pfsync_sendout(), however tell it
not to schedule swi again.
- Since now we don't obtain the pfsync lock in the swi handler,
don't use ifqueue mutex to synchronize queue access.

remove prototypes of a bunch of functions that had their implementations
removed in pfsync v5.
o Make the pfsync.ko actually usable. Before this change loading it
didn't register protosw, so was a nop. However, a module /boot/kernel
did confused users.
o Rewrite the way we are joining multicast group:
- Move multicast initialization/destruction to separate functions.
- Don't allocate memory if we aren't going to join a multicast group.
- Use modern API for joining/leaving multicast group.
- Now the utterly wrong pfsync_ifdetach() isn't needed.
o Move module initialization from SYSINIT(9) to moduledata_t method.
o Refuse to unload module, unless asked forcibly.
o Improve a bit some FreeBSD porting code:
- Use separate malloc type.
- Simplify swi sheduling.
This change is probably wrong from VIMAGE viewpoint, however pfsync
wasn't VIMAGE-correct before this change, too.

only keep track of the number of updates on tcp connections. state sync on
all the other protocols is simply pushing the timeouts along which has a
resolution of 1 second, so it isnt going to be hurt by pfsync taking up
to a second to send it over.
keep track of updates on tcp still though, their windows need constant
attention.
