net: add IEEE 802.15.4 socket family implementation
Add support for communication over IEEE 802.15.4 networks. This implementation
is neither certified nor complete, but aims to that goal. This commit contains
only the socket interface for communication over IEEE 802.15.4 networks.
One can either send RAW datagrams or use SOCK_DGRAM to encapsulate data
inside normal IEEE 802.15.4 packets.
Configuration interface, drivers and software MAC 802.15.4 implementation will
follow.
Initial implementation was done by Maxim Gorbachyov, Maxim Osipov and Pavel
Smolensky as a research project at Siemens AG. Later the stack was heavily
reworked to better suit the linux networking model, and is now maitained
as an open project partially sponsored by Siemens.

pkt_sched: Change PSCHED_SHIFT from 10 to 6
Change PSCHED_SHIFT from 10 to 6 to increase schedulers time
resolution. This will increase 16x a number of (internal) ticks per
nanosecond, and is needed to improve accuracy of schedulers based on
rate tables, like HTB, TBF or CBQ, with rates above 100Mbit. It is
assumed this change is safe for 32bit accounting of time diffs up
to 2 minutes, which should be enough for common use (extremely low
rate values may overflow, so get inaccurate instead). To make full
use of this change an updated iproute2 will be needed. (But using
older iproute2 should be safe too.)
This change breaks ticks - microseconds similarity, so some minor code
fixes might be needed. It is also planned to change naming adequately
eg. to PSCHED_TICKS2NS() etc. in the near future.

be2net: Remove unnecessary frag list traversing.
This driver does not indicate support for frag lists.
Furthermore, even if it did, the code is walking the frag
lists incorrectly. The idiom is:
for (iter = skb_shinfo(skb)->frag_list; iter; iter = iter->next)
but it's doing:
for (iter = skb_shinfo(skb)->frag_list; iter;
iter = skb_shinfo(iter)->frag_list)
which would never work. And this proves that this driver never
saw an SKB with active frag lists.
So just remove the code altogether and the driver TX path becomes

declance: Restore tx descriptor ring locking
A driver overhaul on 29 Feb 2000 (!) broke locking around fiddling with
the tx descriptor ring in start_xmit(); a follow-on "fix" removed the
broken remnants altogether. Here's a patch to restore proper locking in
the function -- the complement in the interrupt handler has been correct
all the time.
This *may* have been the reason for the occasional confusion of the chip
-- triggering a tx timeout followed by a chip reset sequence -- seen on
R4k-based DECstations with the onboard Ethernet interface. Another theory
is the confusion is due to an unindentified problem -- perhaps a silicon
erratum -- associated with the variation of the MT ASIC used to interface
the R4k CPU to the rest of the system on these computers; with its
aggressive write-back buffering the design is particularly weakly ordered
when it comes to MMIO (in the absence of ordering barriers uncached reads
are allowed to bypass earlier uncached writes, even if to the same
location), which may trigger all kinds of corner cases in peripheral
hardware as well as software.
Either way this piece of code is buggy.

the existing connection disassociates and led off command is sent

Patch fixes this by just avoiding sending the led off/on command when

is to start or stop the blinking.
There are three states in led
1) Always on when radio is on
2) Always off when radio is off
3) blink when associated and if there is some traffic.
In this callback 'allow_blinking' needs to be set false

ath9k: Fix write callback of 'debug' which configures debug mask
Handle error condition on copy_from_user() properly and
make sure a NUL terminated char[] is sent to strict_strtoul()
for proper conversion.

iwm: port to new cfg80211 rfkill
Which means removing all rfkill code since it only does
soft-kill which cfg80211 will now handle in exactly the
same way the driver did.

cfg80211: add rfkill support
To be easier on drivers and users, have cfg80211 register an
rfkill structure that drivers can access. When soft-killed,
simply take down all interfaces; when hard-killed the driver
needs to notify us and we will take down the interfaces
after the fact. While rfkilled, interfaces cannot be set UP.
