packet.
rtl8192cu can't connect to AP after physical reconnect.
according to dmesg, that problem's cause was DHCP timeout.
rtl_is_special_data function checks packet type for adjusting rate.
when that function is called from _rtl_rc_get_highest_rix, it can not
calculate offset correctly. so i add argument is_encn in rtl_is_special_data.
is_enc variable mean that iv header is added in skb parameter.
i test only rtl8192cu chipset. because i doesn't have other rtlwifi chipsets.

As the driver may send multiple wmi commands with identical cmd id,
it is more robust to check seq number for timeout instead.

The majority of Intel Bluetooth vendor commands are shared between USB

Future H:4 based UART drivers require custom packet types and custom
receive functions. To support this, extended the h4_recv_buf function
with a packet definition table.
For the default H:4 packets types of ACL data, SCO data and events,
provide helpers to reduce the amount of code duplication.

The hci_recv_stream_fragment function should have never been introduced
in the first place. The Bluetooth core does not need to know anything
about the HCI transport protocol.
With all transport protocol specific detailed moved back into the
drivers where they belong (mainly generic USB and UART drivers), this
function can now be removed.
This reduces the size of hci_dev structure and also removes an exported
symbol from the Bluetooth core module.

This adds a new HCI_UART_VND_DETECT flag to allow automatic vendor

for setting the public device address) when using a standard H:4
UART protocol or when running in virtual machines.
When this new flag is configured and no vendor specific setup
routine is provided, then the local version information are read
and the provided manufacturer information can be evaluated to
configure extra vendor callbacks.

Every tracing file must have its own TRACE_SYSTEM defined.
The mac80211 tracepoint header broke this and add in the middle
of the file had:
#undef TRACE_SYSTEM
#define TRACE_SYSTEM mac80211_msg
Unfortunately, this broke new code in the ftrace infrastructure.
Moving the mac80211_msg into its own trace file with its own
TRACE_SYSTEM defined fixes the issue.

The tracing infrastructure is adding a macro TRACE_SYSTEM_STRING, and
hit the following build failure:

Seems that the DRM folks have added their own use to the
TRACE_SYSTEM_STRING, with:
#define TRACE_SYSTEM_STRING __stringify(TRACE_SYSTEM)
Although, I can not find its use anywhere. I could simply use another
name, but if this macro is not being used, it should be removed.

This reverts commit 89baaa570ab0b476db09408d209578cfed700e9f.
Dirty page throttling should be sufficient for us in the general case
so there is no need to use __GFP_MEMALLOC - it would be needed only in
the swap-over-rbd case, which we currently don't support. (It would
probably take approximately the commit that is being reverted to add
that support, but we would also need the "swap" option to distinguish
from the general case and make sure swap ceph_client-s aren't shared
with anything else.) See ceph-devel threads [1] and [2] for the
details of why enabling pfmemalloc reserves for all cases is a bad
thing.
On top of potential system lockups related to drained emergency
reserves, this turned out to cause ceph lockups in case peers are on
the same host and communicating via loopback due to sk_filter()
dropping pfmemalloc skbs on the receiving side because the receiving
loopback socket is not tagged with SOCK_MEMALLOC.

- New HCI request callback type to get the resulting skb
- Cleanups to use BIT() macro wherever possible
- Consolidate Broadcom device entries in the btusb HCI driver
- Check for valid flags in CMTP, HIDP & BNEP
- Disallow local privacy & OOB data combo to prevent a potential race
- Expose SMP & ECDH selftest results through debugfs
- Expose current Device ID info through debugfs
