config_intrhook_drain will remove the hook from the list as
config_intrhook_disestablish does if the hook hasn't been called. If it has,
config_intrhook_drain will wait for the hook to be disestablished in the normal
course (or expedited, it's up to the driver to decide how and when
to call config_intrhook_disestablish).
This is intended for removable devices that use config_intrhook and might be
attached early in boot, but that may be removed before the kernel can call the
config_intrhook or before it ends. To prevent all races, the detach routine will
need to call config_intrhook_train.

This is a prerequisite to allowing the use of hardware watchpoints for
userspace debuggers.
This is also a slight departure from the x86 behaviour, since `si_addr`
returns the data address that triggered the watchpoint, not the
address of the instruction that was executed. Otherwise, there is no
straightforward way for the application to determine which watchpoint
was triggered. Make a note of this in the siginfo(3) man page.

Currently, OpenCrypto consumers can request asynchronous dispatch by
setting a flag in the cryptop. (Currently only IPSec may do this.) I
think this is a bit confusing: we (conditionally) set cryptop flags to
request async dispatch, and then crypto_dispatch() immediately examines
those flags to see if the consumer wants async dispatch. The flag names
are also confusing since they don't specify what "async" applies to:
dispatch or completion.
Add a new KPI, crypto_dispatch_async(), rather than encoding the
requested dispatch type in each cryptop. crypto_dispatch_async() falls
back to crypto_dispatch() if the session's driver provides asynchronous
dispatch. Get rid of CRYPTOP_ASYNC() and CRYPTOP_ASYNC_KEEPORDER().
Similarly, add crypto_dispatch_batch() to request processing of a tailq
of cryptops, rather than encoding the scheduling policy using cryptop
flags. Convert GELI, the only user of this interface (disabled by
default) to use the new interface.
Add CRYPTO_SESS_SYNC(), which can be used by consumers to determine
whether crypto requests will be dispatched synchronously. This is just
a helper macro. Use it instead of looking at cap flags directly.
Fix style in crypto_done(). Also get rid of CRYPTO_RETW_EMPTY() and
just check the relevant queues directly. This could result in some
unnecessary wakeups but I think it's very uncommon to be using more than
one queue per worker in a given workload, so checking all three queues
is a waste of cycles.

Handling of unknown MACs on an bridge with incomplete learning
capabilites (aka uplink ports) can be defined in different ways.
The classical approach is to broadcast unicast frames send to an
unknown MAC, because the unknown devices can be everywhere. This mode
is default for ng_bridge(4).
In the case of dedicated uplink ports, which prohibit learning of MAC
addresses in order to save memory and CPU cycles, the broadcast
approach is dangerous. All traffic to the uplink port is broadcasted
to every downlink port, too. In this case, it's better to restrict the
distribution of frames to unknown MAC to the uplink ports only.
In order to keep the chance small and the handling as natural as
possible, the first attached link is used to determine the behaviour
of the bridge: If it is an "uplink" port, then the bridge switch from
classical mode to restricted mode.

The ng_bridge(4) node is designed to work in moderately small
environments. Connecting such a node to a larger network rapidly fills
the MAC table for no reason. It even become complicated to obtain data
from the gettable message, because the result is too large to
transmit.
This patch introduces, two new functionality bits on the hooks:
- Allow or disallow MAC address learning for incoming patckets.
- Allow or disallow sending unknown MACs through this hook.
Uplinks are characterized by denied learing while sending out
unknowns. Normal links are charaterized by allowed learning and
sending out unknowns.
