Firmware was crashing when we were trying to warm reset it
after suspend. This was due to the fact that target registeres
can be accessed only if the hardware is awaken.
This patch makes sure to awake the device also on the hif up,
not only in case of probe call.

Existing implementation of reset_resume handler just calls
ath6kl_usb_remove() that deallocates all resources.
It can lead to double free, etc. on disconnect.
The patch removes reset_resume handler,
so usb core could conservatively reset the driver.

This patch adds an ieee802154_ptr to the net_device structure.
Furthermore the 802.15.4 subsystem will introduce a nl802154 framework
which is similar like the nl80211 framework and a wpan_dev structure.
The wpan_dev structure will hold additional net_device attributes like
address options which are 802.15.4 specific. In the upcoming nl802154
implementation we will introduce a NL802154_FLAG_NEED_WPAN_DEV like
NL80211_FLAG_NEED_WDEV. For this flag an ieee802154_ptr in net_device is
needed. Additional we can access the wpan_dev attributes in upper layers
like IEEE 802.15.4 6LoWPAN easily. Current solution is a complicated
callback interface and getting these values over subif data structure
in mac802154.

According to Management Interface API 'Start Discovery' command should
generate a Command Complete event on failure. Currently kernel is
sending Command Status on early errors. This results in userspace
ignoring such event due to invalid size.

The debufs entry for the BR/EDR whitelist is confusing since there is
a controller debugfs entry with the name white_list and both are two
different things.
With the BR/EDR whitelist, the actual interface in use is the device
list and thus just include all values from the internal BR/EDR whitelist
in the device_list debugfs entry.

Some vendors decide to use a strict duplicate filter policy that only
filters on Bluetooth device addresses. This means that when the RSSI
changes, these devices are not reported again. During discovery it is
useful to actually get the RSSI updates.
Since this is specific to each controller, add a new quirk setting
that allows drivers to tell the core what kind of filtering policy
the controller uses.

When the HCI_Reset command returns, the status needs to be checked. It
is unlikely that HCI_Reset actually fails, but when it fails, it is a

All PHY attributes should be directly set to the transceiver after netlink.
MAC attributes should be set by interface up. Currently the macparams
netlink cmd contains mixed attributes of phy and mac settings. This patch

This is the only way which doesn't change the userspace API and keep the

H5 Specification says:
If a SYNC message is received while in the Active State, it is
assumed that the peer device has reset. The local device should
therefore perform a full reset of the upper stack, and start Link
Establishment again at the Uninitialized State. Upon entering the
Active State, the first packet sent shall have its SEQ and ACK
numbers set to zero.
This patch resets the HCI H5 driver data/state to unitialized and
reports an HCI hardware error event to notify the upper stack that
HCI synchronization has been lost. H5 will be re-synchronized and
upper stack should generate an HCI Reset command.

Instead of waiting for inevitable timeouts poke

While testing other things I've found that CE
items aren't cleared properly. This could lead to
null dereferences in BMI.
To prevent that make sure CE revoking clears the
nbytes value (which is used as a buffer completion
indication) and memset the entire CE ring data
shared between host and target when
(re)initializing.
Also make sure to check BMI xfer pointer and print
a splat instead of crashing the kernel.
