This is required for (more) correct TDMA support. Without it, the
code tries to calculate the required guard interval based on the
current rate, and since this is an 11n NIC and people try using
11n, it calls ath_hal_computetxtime() on an 11n rate which then
panics.
This doesn't fix TDMA slave mode on AR9300 - it just makes it
have one less bug.

Futex object scopes have been renamed from using their own constants to
simply reusing the existing CLOUDABI_MAP_{PRIVATE,SHARED} flags, as they
are more accurate in this context.
Add support for the <sys/mman.h> functions by wrapping around our own
implementations. There are no kern_*() variants of these system calls,
but we also don't need them in this case. It is sufficient to just call
into the sys_*() functions.

Summary:
For CloudABI we need to put two things on the stack of new processes:
the argument data (a binary blob; not strings) and a startup data
structure. The startup data structure contains interesting things such
as a pointer to the ELF program header, the thread ID of the initial
thread, a stack smashing protection canary, and a pointer to the
argument data.
Fetching system call arguments and setting the return value is similar
to FreeBSD. The only differences are that system call 0 does not exist
and that we call into cloudabi_convert_errno() to convert the error
code. We also need this function in a couple of other places, so we'd
better reuse it here.

CloudABI is a pure capability-based runtime environment for UNIX. It
works similar to Capsicum, except that processes already run in
capabilities mode on startup. All functionality that conflicts with this
model has been omitted, making it a compact binary interface that can be
supported by other operating systems without too much effort.
CloudABI is 'secure by default'; the idea is that it should be safe to
run arbitrary third-party binaries without requiring any explicit
hardware virtualization (Bhyve) or namespace virtualization (Jails). The
rights of an application are purely determined by the set of file
descriptors that you grant it on startup.
The datatypes and constants used by CloudABI's C library (cloudlibc) are
defined in separate files called syscalldefs_mi.h (pointer size
independent) and syscalldefs_md.h (pointer size dependent). We import
these files in sys/contrib/cloudabi and wrap around them in
cloudabi*_syscalldefs.h.
We then add stubs for all of the system calls in sys/compat/cloudabi or
sys/compat/cloudabi64, depending on whether the system call depends on
the pointer size. We only have nine system calls that depend on the
pointer size. If we ever want to support 32-bit binaries, we can simply
add sys/compat/cloudabi32 and implement these nine system calls again.
The next step is to send in code reviews for the individual system call
implementations, but also add a sysentvec, to allow CloudABI executabled
to be started through execve().

* an external XLNA hooked up to a GPIO pin;
* (and not yet done) RSSI threshold differences when

To make this possible:

* .. and until FreeBSD learns about a PCI device list like this,

- Stateful TCP offload drivers for Terminator 3 and 4 (T3 and T4) ASICs.
These are available as t3_tom and t4_tom modules that augment cxgb(4)
and cxgbe(4) respectively. The cxgb/cxgbe drivers continue to work as
usual with or without these extra features.
- iWARP driver for Terminator 3 ASIC (kernel verbs). T4 iWARP in the
works and will follow soon.
Build-tested with make universe.
30s overview
============
What interfaces support TCP offload? Look for TOE4 and/or TOE6 in the
capabilities of an interface:
# ifconfig -m | grep TOE
Enable/disable TCP offload on an interface (just like any other ifnet
capability):
# ifconfig cxgbe0 toe
# ifconfig cxgbe0 -toe
Which connections are offloaded? Look for toe4 and/or toe6 in the
output of netstat and sockstat:
# netstat -np tcp | grep toe
# sockstat -46c | grep toe

Impact is that the "flush" keyword didn't work.

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.

Temporarily revert an upstream commit. This change caused regressions for
too many laptop users. Especially, automatic repair for broken _BIF caused
strange reference counting issues and kernal panics. This reverts:

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.
