AX25 already has it's own private arp cache operations to isolate
it's abuse of dev_rebuild_header to transmit packets. Add a function
ax25_neigh_construct that will allow all of the ax25 devices to
force using these operations, so that the generic arp code does
not need to.

Not setting the destination address is a bug that I suspect causes no
problems today, as only the arp code seems to call dev_hard_header and
the description I have of rose is that it is expected to be used with a
static neigbour table.
I have derived the offset and the length of the rose destination address
from rose_rebuild_header where arp_find calls neigh_ha_snapshot to set
the destination address.

Masami noted that it would be better to hide the remaining CONFIG_BPF_SYSCALL-only
function declarations within the BPF header ifdef, w/o else path dummy alternatives
since these functions are not supposed to have a user outside of CONFIG_BPF_SYSCALL.

Netfilter updates for net-next
A small batch with accumulated updates in nf-next, mostly IPVS updates,
they are:
1) Add 64-bits stats counters to IPVS, from Julian Anastasov.
2) Move NETFILTER_XT_MATCH_ADDRTYPE out of NETFILTER_ADVANCED as docker
seem to require this, from Anton Blanchard.
3) Use boolean instead of numeric value in set_match_v*(), from
coccinelle via Fengguang Wu.
4) Allows rescheduling of new connections in IPVS when port reuse is
detected, from Marcelo Ricardo Leitner.
5) Add missing bits to support arptables extensions from nft_compat,
from Arturo Borrero.
Patrick is preparing a large batch to enhance the set infrastructure,
named expressions among other things, that should follow up soon after
this batch.

Currently, when TCP/SCTP port reusing happens, IPVS will find the old
entry and use it for the new one, behaving like a forced persistence.
But if you consider a cluster with a heavy load of small connections,
such reuse will happen often and may lead to a not optimal load
balancing and might prevent a new node from getting a fair load.
This patch introduces a new sysctl, conn_reuse_mode, that allows
controlling how to proceed when port reuse is detected. The default
value will allow rescheduling of new connections only if the old entry
was in TIME_WAIT state for TCP or CLOSED for SCTP.

IPVS stats are limited to 2^(32-10) conns/s and packets/s,
2^(32-5) bytes/s. It is time to use 64 bits:
* Change all conn/packet kernel counters to 64-bit and update
them in u64_stats_update_{begin,end} section
* In kernel use struct ip_vs_kstats instead of the user-space
struct ip_vs_stats_user and use new func ip_vs_export_stats_user
to export it to sockopt users to preserve compatibility with
32-bit values
* Rename cpu counters "ustats" to "cnt"
* To netlink users provide additionally 64-bit stats:
IPVS_SVC_ATTR_STATS64 and IPVS_DEST_ATTR_STATS64. Old stats
remain for old binaries.
* We can use ip_vs_copy_stats in ip_vs_stats_percpu_show

While testing I experience a deadlock while using the at86rf233 on a
raspberry pi. The reason was an edge triggered gpio irq because the irq
triggered while irq was disabled. This issue doesn't happend on a level
triggered irq because the irq will hit after calling enable_irq.
This patch adds a warning that it's not recommended to use a edge-triggered
irq type. Also change the examples to high-level irqtype.

The only reason the SMP code is essentially duplicating the
hci_copy_identity_addr() function is that the helper returns the address
type in the HCI format rather than the three-value format expected by

do a simple conversion from one address type to another.

When processing hci_cb entries we want first registered callbacks to be
called first and later ones later. This is because eventually the L2CAP
callbacks that are part of the core will use this list and get
registered first. To keep the same order of calling L2CAP callbacks
before e.g. RFCOMM the order of elements needs to be this way.

Some AMP controllers do not support the Read Local Features HCI commands

On BR/EDR the L2CAP channel instances for fixed channels have so far
been marked as ready only once the L2CAP information req/rsp procedure
is complete and we have the fixed channel mask. This could however lead
to data being dropped if we receive it on the channel before knowing the
remote mask.
Since it is valid for a remote to send data this early, simply assume
that the channel is supported when we receive data on it. So far this
hasn't been noticed much because of limited use of fixed channels on
BR/EDR, but e.g. with SMP over BR/EDR this is already now visible with
automated tests failing randomly.

The Broadcom firmware files are named with firmware version information
encoded into lmp_subver field. So BCM20702B0_002.001.014.0527.0607.hex
would be represented by 0x410e. To allow for an easier decoding of the
actual firmware names, provide an internal table that does the mapping
and request the firmware file by name.
Bluetooth: hci0: BCM20702B0 (002.001.014) build 0607
Now the complicated encoding of lmp_subver will be decoded and turned
into the name and firmware version information from the firmware files.
The previous attempt of using udev->product failed badly since it never
contains any matching entry to the actual hardware or firmware files
distributed by Broadcom in their Windows drivers. It is even worse since
it can change depending on if the internal bootstrapping happened before
the USB bus enumeration or after. This caused many race conditions.

Add 04f2:aff1 to ath3k.c supported devices list and btusb.c blacklist, so
that the device can load the ath3k firmware and re-enumerate itself as an
AR3011 device.

This patch adds the device shutdown routine for Intel Bluetooth device.
Some platforms have BT LED issue with Intel Bluetooth device that BT LED goes
off 5 seconds after BT is turned off
For Intel Bluetooth device, the BT LED is turned off when:
- there is no active connection or radio activity
- USB is suspend
So, when the BT is turned off, it takes 5 seconds because USB suspend timeone
is 5 seconds by default. And if the USB suspend is not enabled, BT LED won't be
turned off.
To fix this issue, recently Intel Bluetooth firmware patch had been submitted
to turn off the BT LED immediately by the vendor specific command(0xFC3F). And
this patch sends this command to the device before closing the device.
For backward compatibility of this command with old firmware, this command was
supported before, but it behaves same as HCI_RESET internally. So, it won't be
the problem even if the system doesn't have the latest firmware patch.

return type of wait_for_completion_timeout is unsigned long not int.
As rc is used here only for wait_for_completion_timeout the type is simply
changed to unsigned long.

This patch adds other known rfc6282 compression formats to the nhc
framework. These compression formats are known but not implemented yet.
For now this is useful to printout a warning which compression format
isn't supported.

This patch move UDP header compression and uncompression into the
generic 6LoWPAN nhc header compression layer. Moreover this patch
activates the nhc layer compression in iphc compression and
uncompression functions.

This patch adds a generic next header compression layer interface. There
exists various methods to do a header compression after 6LoWPAN header
to save payload. This introduce a generic nhc header which allow a
simple adding of a new header compression format instead of a static
implementation inside the 6LoWPAN header compression and uncompression
function.
