Johannes Berg <johannes@sipsolutions.net> says:
"Here are a few fixes for the wireless stack: one fixes the
RTS rate, one for a debugfs file, one to return the correct
channel to userspace, a sanity check for a userspace value
and the remaining two are just documentation fixes."

This patch changes the naming convention of mac802154 rx file. It should
be more named like mac80211 stack. Furthermore we introduce a new frame

implementation.

This removes the call of monitor receive funktion when any interface
type call xmit. There exist no such use case that a monitor interface
should receive the actual sending frame. One use case could be that a
wpan interface and monitor interface could be running at the same time
on one phy. Then the monitor interface receives the wpan frames also.
Furthermore we adding support for promiscous mode setting. With
promiscous mode setting we can't run a wpan and monitor interface at the
same time.

Tasklets have much less overhead than workqueues. This patch also
removes the heap allocation for the worker on receiving path.
Like mac80211 we should prefer use a tasklet here instead a workqueue to
getting fast out of interrupt context when ieee802154_rx_irqsafe is
called by driver. Like wireless inside the tasklet context we should
call netif_receive_skb instead netif_rx_ni anymore.

When CONFIG_MAC80211_RC_MINSTREL_VHT is set, the module param
minstrel_vht_only tells minstrel_ht whether to allow the mix of ht rates
with vht rates.
ATM, minstrel_ht skips ht rates when minstrel_vht_only is true, but it does
that even if vht is not supported, which makes the sta rates fallback to
legacy as no ht rate gets enabled.

All the callers of ieee80211_mgd_probe_ap_send return right
after they call the flush() callback. This means that calling
flush() is uneeded since its meaning is to wait until the
queues of the device are empty.
Devices that know how to report status on Tx will do so using
the regular path (ieee80211_tx_status) and this status will
trigger the continuation of the flow of the probe
(ieee80211_sta_tx_notify).

This patch moves the worker information struct out of skb control block.
Instead control block we declare it static inside of tx.c file. We can do
that, because the worker can't be used twice at the same time. It's
protected by stop and wake netdev queue.
This patch fix an issue that the "struct ieee802154_xmit_cb" doesn't fit
into the skb control block on some kernel configuartion reported by
kbuild test robot.
It was introduced by commit fe24371d6645b766c59ec664c59d0a9c310ad455

This patch removes the channel hopping feature before xmit. There are
several issues to provide a real channel hopping (timing requirements,
etc...).
We don't have any known kernelspace protocol which really use this

We simply drop this feature now.

percpu tcp_md5sig_pool contains memory blobs that ultimately
go through sg_set_buf().
-> sg_set_page(sg, virt_to_page(buf), buflen, offset_in_page(buf));
This requires that whole area is in a physically contiguous portion
of memory. And that @buf is not backed by vmalloc().
Given that alloc_percpu() can use vmalloc() areas, this does not
fit the requirements.
Replace alloc_percpu() by a static DEFINE_PER_CPU() as tcp_md5sig_pool
is small anyway, there is no gain to dynamically allocate it.
