This patches moves the debugfs interface related register after
netdevice register. The function lowpan_dev_debugfs_init will use
"dev->name" which can be before register_netdevice a format string.
The function register_netdevice will evaluate the format string if
necessary and replace "dev->name" to the real interface name.

This patch reworks the handling of compression/decompression of traffic
class and flow label handling. The current method is hard to understand,
also doesn't checks if we can read the buffer from skb length.
I tried to put the shifting operations into static inline functions and
comment each steps which I did there to make it hopefully somewhat more
readable. The big mess to deal with that is the that the ipv6 header
bring the order "DSCP + ECN" but iphc uses "ECN + DSCP". Additional the
DCSP + ECN bits are splitted in ipv6_hdr inside the priority and
flow_lbl[0] fields.
I tested these compressions by using fakelb 802.15.4 driver and
manipulate the tc and flow label fields manually in function
"__ip6_local_out" before the skb will be send to lower layers. Then I
looked up the tc and flow label fields in wireshark on a wpan and lowpan
interface.

This patch has the main goal to delete shift operations. Instead we
doing masks and equals afterwards. E.g. for the SAM evaluation we
masking only the SAM value which fits in iphc1 byte, then comparing with
all possible SAM values over a switch case statement. We will not
shifting the SAM value to somewhat readable anymore.
Additional this patch slighty change the naming style like RFC 6282,
e.g. TTL to HLIM and we will drop an errno now if CID flag is set,
because we don't support it.

This patch changes the lowpan_header_decompress function by removing
inklayer related information from parameters. This is currently for
supporting short and extended address for iphc handling in 802154.
We don't support short address handling anyway right now, but there
exists already code for handling short addresses in
lowpan_header_decompress.
The address parameters are also changed to a void pointer, so 6LoWPAN
linklayer specific code can put complex structures as these parameters
and cast it again inside the generic code by evaluating linklayer type
before. The order is also changed by destination address at first and
then source address, which is the same like all others functions where
destination is always the first, memcpy, dev_hard_header,
lowpan_header_compress, etc.
This patch also moves the fetching of iphc values from 6LoWPAN linklayer
specific code into the generic branch.

This patch cleanups needed_headroom, needed_tailroom and hard_header_len
fields for wpan and lowpan interfaces.
For wpan interfaces the worst case mac header len should be part of
needed_headroom, currently this is set as hard_header_len, but
hard_header_len should be set to the minimum header length which xmit
call assumes and this is the minimum frame length of 802.15.4.
The hard_header_len value will check inside send callbacl of AF_PACKET
raw sockets.
For lowpan interfaces, if fragmentation isn't needed the skb will
call dev_hard_header for 802154 layer and queue it afterwards. This
happens without new skb allocation, so we need the same headroom and
tailroom lengths like 802154 inside 802154 6lowpan layer. At least we
assume as minimum header length an ipv6 header size.

For the NFC bits, Samuel says:
"This is a rather quiet one, we have:
- A new driver from ST Microelectronics for their NCI ST21NFCB,
including device tree support.
- p2p support for the ST21NFCA driver
- A few fixes an enhancements for the NFC digital laye"
For the Atheros bits, Kalle says:
"Michal and Janusz did some important RX aggregation fixes, basically we
were missing RX reordering altogether. The 10.1 firmware doesn't support
Ad-Hoc mode and Michal fixed ath10k so that it doesn't advertise Ad-Hoc
support with that firmware. Also he implemented a workaround for a KVM
issue."
For the Bluetooth bits, Gustavo and Johan say:
"To quote Gustavo from his previous request:
'Some last minute fixes for -next. We have a fix for a use after free in
RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with
auto-connection handling. Last, we added support for reading the codec and
MWS setting for controllers that support these features.'
Additionally there are fixes to LE scanning, an update to conform to the 4.1
core specification as well as fixes for tracking the page scan state. All
of these fixes are important for 3.17."
And,
"We've got:
- 6lowpan fixes/cleanups
- A couple crash fixes, one for the Marvell HCI driver and another in LE SMP.
- Fix for an incorrect connected state check
- Fix for the bondable requirement during pairing (an issue which had
crept in because of using "pairable" when in fact the actual meaning
was "bondable" (these have different meanings in Bluetooth)"
Along with those are some late-breaking hardware support patches in
brcmfmac and b43 as well as a stray ath9k patch.

This patch moves generic code which is used by bluetooth and ieee802154
6lowpan to a new net/6lowpan directory. This directory contains generic
6LoWPAN code which is shared between bluetooth and ieee802154 MAC-Layer.
This is the IPHC - "IPv6 Header Compression" format at the moment. Which
is described by RFC 6282 [0]. The BLTE 6LoWPAN draft describes that the
IPHC is the same format like IEEE 802.15.4, see [1].
Futuremore we can put more code into this directory which is shared
between BLTE and IEEE 802.15.4 6LoWPAN like RFC 6775 or the routing
protocol RPL RFC 6550.
To avoid naming conflicts I renamed 6lowpan-y to ieee802154_6lowpan-y
in net/ieee802154/Makefile.
