taskqueue_start_threads(struct taskqueue **, int count, int pri,
const char *name, ...);
This allows the creation of 1 or more threads that will service a single
taskqueue. Also rework the taskqueue_create() API to remove the API change
that was introduced a while back. Creating a taskqueue doesn't rely on
the presence of a process structure, and the proc mechanics are much better
encapsulated in taskqueue_start_threads(). Also clean up the
taskqueue_terminate() and taskqueue_free() functions to safely drain
pending tasks and remove all associated threads.
The TASKQUEUE_DEFINE and TASKQUEUE_DEFINE_THREAD macros have been changed
to use the new API, but drivers compiled against the old definitions will
still work. Thus, recompiling drivers is not a strict requirement.

ipxpcb is NULL or not: in attach it will be, and on detach it won't be.
If for any reason these invariants don't hold true, panicking is a good
idea.

no need to have mcopy, conditionally look at mcopy, or conditionally free
it.

ef_clone(); we were testing the original ifnet, not the one allocated.
When aborting ef_clone() due to if_alloc() failing, free the allocated
efnet structure rather than leaking it.

SLIST_FOREACH_SAFE() rather than SLIST_FOREACH(), as elements are
freed on each iteration of the loop. This prevents use-after-free.

intended for use solely with atomic datagram socket types, and relies
on the previous break-out of sosend_copyin(). Changes to allow UDP to
optionally use this instead of sosend() will be committed as a
follow-up.
2) use more robust way of link state handling for BCM5700 rev.B2 chip
3) workaround bug of some BCM570x chips which cause spurious "link up" messages
4) fix bug: some BCM570x chips was unable to detect link state changes after
ifconfig down/up sequence until any 'non-link related' interrupt generated.
(this happened due to pending internal link state attention which blocked
interrupt generation)

have worked before, but it should be fixed now. Also break out the interrupt

use default zero flags. This removes unpleasant contention of the

mutex).

* fix bst.rate to correctly output the (dis)charging rate. We'll use
the current average over one minute command and not the at_rate command.
Note that this method is not correct if the capacity_mode is set, but
since we don't set it ourself, it is not a problem.
The at_rate do not give the actual rate but is used to compute the
estimated time for (dis)charging a battery. We should actually
write an estimation of the actual rate using at_rate cmd and then
perform a read to the various estimators.

had been replied, the reply was always delivered to the originator
synchronously.
With introduction of netgraph item callbacks and a wait channel with
mutex in ng_socket(4), we have fixed the problem with ngctl(8) returning
earlier than the command has been proceeded by target node. But still
ngctl(8) can return prior to the reply has arrived to its node.
To fix this:
- Introduce a new flag for netgraph(4) messages - NGM_HASREPLY.
This flag is or'ed with message like NGM_READONLY.
- In netgraph userland library if we have sent a message with
NGM_HASREPLY flag, then select(2) until reply comes.
- Mark appropriate generic commands with NGM_HASREPLY flag,
gathering them into one enum {}. Bump generic cookie.
