2) Remove bogus code, which can lead to a panic as it calls
kern_sigtimedwait with same ksiginfo.
3) Return the corresponding signal number.
little further. This gets us further on the way to be able to build it
successfully with clang. Using in-tree gcc, this shrinks boot2.bin with
60 bytes, the in-tree clang shaves off 72 bytes, and ToT clang 84 bytes.

caused link re-negotiation whenever application joins or leaves a
multicast group. If driver is running, it would have established a
link so there is no need to start re-negotiation. The re-negotiation
broke established link which in turn stopped multicast application
working while re-negotiation is in progress.

vm_map_insert(), the kmem_back() assumption about newly inserted
entry might be broken due to interference of two factors. In the low
memory condition, when vm_page_alloc() returns NULL, supplied map is
unlocked. If another thread performs kmem_malloc() meantime, and its
map entry is placed right next to our thread map entry in the map,
both entries wire count is still 0 and entries are coalesced due to
vm_map_simplify_entry().
Mark new entry with MAP_ENTRY_IN_TRANSITION to prevent coalesce.
Fix some style issues, tighten the assertions to account for
MAP_ENTRY_IN_TRANSITION state.

Catch a set vnet upon return to user space. This usually
means return paths with CURVNET_RESTORE() missing.
If VNET_DEBUG is turned on we can even tell the function
that did the CURVNET_SET() which is really helpful; else
we print "N/A".

While updating Tx stats, already freed node could be referred and cause
page fault. To avoid such panic, spool Tx stats in driver's softc. Then,
on every ratectl interval, grab node though ieee80211_iterate_nodes() and

The algorithm is supposed to work as follows:
in order to prevent starvation, when a new client starts being served we
record the start time and reset the counter of bytes served.
We then switch to a new client after a certain amount of time or bytes,
even if the current one still has pending requests.
To avoid charging a new client the time of the first seek,
we start counting time when the first request is served.
Unfortunately a bug in the previous version of the code failed
to set the start time in certain cases, resulting in some processes
exceeding their timeslice.
The fix (in this patch) is trivial, though it took a while to find
out and replicate the bug.
Thanks to Tommaso Caprai for investigating and fixing the problem.
