when workqs were introduced, we provided a second argument so you
could pass a thing and some context to work on it in. there were
very few things that took advantage of the second argument, so when
i introduced pools i suggested removing it. since tasks were meant
to replace workqs, it was requested that we keep the second argument
to make porting from workqs to tasks easier.
now that workqs are gone, i had a look at the use of the second
argument again and found only one good use of it (vdsp(4) on sparc64
if you're interested) and a tiny handful of questionable uses. the
vast majority of tasks only used a single argument. i have since
modified all tasks that used two args to only use one, so now we
can remove the second argument.
so this is a mechanical change. all tasks only passed NULL as their
second argument, so we can just remove it.

response is received from a node. Only call it once when the node is
initially discovered, as used to be the case before r1.4 of this file.
Asking the driver to set up its per-node private state once is enough.
Also remove an outdated comment.

strengths on 802.11 interfaces. ok stsp@
Power on wireless interfaces is usually scaled in dBm. rssi (received signal
strength) is expected to be a -ve dBm values (i.e. [much] <1mW). Some (though
not all!) drivers store this as negative values, so it needs to be passed to
ifconfig that way for printing, not cast to an unsigned value. Valid range is
something like -40 to -90dBm, so the range available with a signed char is
reasonable whether it's stored as a +ve or -ve number.

* SIOCG80211ALLNODES operates on struct ieee80211_nodereq_all, not
struct ieee80211_nodereq.
* Six SIOC* from wi(4) were using same codes with generic parts of
IEEE 802.11 framework. Things worked due to the fact that size
of data struct being passed is encoded in actual SIOC*, too.
This commit means that ifconfig and some ports will need to be rebuilt,
if any of affected SIOC* codes is used. Port bumps to follow.

Since struct ieee80211_nodereq grows in size old ifconfig won't be
able to scan when running on a new kernel.

of to the bridge itself. This is ok, since an interface can only be part
of one bridge, and the parent bridge is easy to find from the bridgeport.
This way we can get rid of a lot of list walks, improving performance

ieee80211_create_ibss() resets the set of supported rates but failed
to update the index into the rate set array accordingly. If the rate
configured during STA operation didn't belong to the newly configured
rate set the system ran into an assertion ("bogus xmit rate %u setup")
while trying to create the IBSS.

in debug mode.
If the interface is in debug mode ieee80211_input() will print messages
about received frames to the console. On slow systems, printf() calls can
take so long that the next RX interrupt will be serviced immediately, if
the RX rate is sufficiently high. This effectively locks the system at IPL_NET.
If a concurrent scan is running, the scan will never finish because it
relies on a timeout at IPL_SOFTCLOCK to hop channels every 200msec.
This timeout never runs in the above situation, leaving the wireless
interface in 'scan' state forever.
To give the timeout a chance to run, perform the printf() call from a
work queue (idea from guenther@). This allows edd's slow soekris AP to
recover from 'ifconfig ral0 debug down up' in noisy RF environments.
With input from guenther, kettenis, blambert and deraadt.

keeping them for the entire cache timeout interval. Fixes association failures

There is no need to keep nodes cached with never associated and were
inactive within the last 5 minutes or more. Keeps the node cache pretty
clean in my environment with typical city-center wlan noise.

Small parts of code for this feature were already present but unused.
A node becomes inactive after not sending or receiving a frame within
5 minutes. Inactive cached nodes (not authenticated or associated) are
automatically cleared from the cache once every hour, making room for
new nodes. If the node cache is full and room must be made for a new node,
clean either a cached node (active or inactive), or an inactive
authenticated or associated node.
Also, do not send de-auth frames to nodes which never authenticated,
and only send a de-auth frame once for a given node.
This part was contributed by Steven Chamberlain, thanks!
Tested by myself, krw@, edd@, Steven Chamberlain, and Markus Schatzl.

and freeing the node. Just in case an interrupt happens to ref the node after
the refcount was checked but before the node is freed.
Tested by several as part of a larger diff.

Check if the node was already cached first. Duplicate nodes aren't reachable
from the node cache's RB tree, so they leak and mess up node cache accounting.
As more and more nodes leak the global nodes counter keeps increasing,
eventually reaching the limit and hovering there. The system then constantly
tries to clean the node cache, sending de-auth frames to stations in the
process, even if the actual number of associated stations is small.

the caller and the function that the function will not fail to allocate
memory and return a NULL pointer. However, m_dup_pkthdr() violates
this contract, making it possible for functions that pass M_WAITOK to
be surprised in ways that hurt.
Fix this by passing the wait flag all the way down the functions that
actually do the allocation for m_dup_pkthdr() so that we won't be
surprised.
