When a response for PS-Poll or a uAPSD trigger frame is sent, the
more-data bit should be set according to 802.11-2012 11.2.1.5 h),
meaning that it should indicate more data on the relevant ACs

In, for example, the following scenario:
* 1 frame on VO queue (either in driver or in mac80211)
* at least 1 frame on VI queue (in the driver)
* both VO/VI are delivery-enabled
* uAPSD trigger frame received
The more-data flag to the driver would not be set, even though
it should be.
While fixing this, I noticed that we should really release frames
from multiple ACs where there's data buffered in the driver for
the corresponding TIDs.
To address all this, restructure the code a bit to consider all
ACs if we only release driver frames or only buffered frames.
This also addresses the more-data bug described above as now the
TIDs will all be marked as released, so the driver will have to
check the number of frames.

My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.

setting Universal/Local bit for the 6loWPAN network device or for the
peer device connection.
ADDR_LE_DEV_PUBLIC or ADDR_LE_DEV_RANDOM are the values allowed for
"src_type" and "dst_type" in the hci_conn struct. The Bluetooth link
type can be obtainned reading the "type" field in the same struct.
Marvell nfc device provides support for external coexistance
control. It allows Device Host to inhibit the NFCC from polling
when required by asserting a GPIO pin. A second pin allows the
DH to have feedback on the current NFCC state.
The required configuration for this feature is done in setup
handler.
Bluetooth: Always wait for a connection on RFCOMM open()
This patch fixes two regressions introduced with the recent rfcomm tty
rework.
The current code uses the carrier_raised() method to wait for the
bluetooth connection when a process opens the tty.
However processes may open the port with the O_NONBLOCK flag or set the
CLOCAL termios flag: in these cases the open() syscall returns
immediately without waiting for the bluetooth connection to
complete.
This behaviour confuses userspace which expects an established bluetooth
connection.
The patch restores the old behaviour by waiting for the connection in
rfcomm_dev_activate() and removes carrier_raised() from the tty_port ops.
As a side effect the new code also fixes the case in which the rfcomm
tty device is created with the flag RFCOMM_REUSE_DLC: the old code
didn't call device_move() and ModemManager skipped the detection
probe. Now device_move() is always called inside rfcomm_dev_activate().
Bluetooth: Release RFCOMM port when the last user closes the TTY
This patch fixes a userspace regression introduced by the commit 29cd718b.
If the rfcomm device was created with the flag RFCOMM_RELEASE_ONHUP the
user space expects that the tty_port is released as soon as the last
process closes the tty.
The current code attempts to release the port in the function
rfcomm_dev_state_change(). However it won't get a reference to the
relevant tty to send a HUP: at that point the tty is already destroyed
and therefore NULL.
This patch fixes the regression by taking over the tty refcount in the
tty install method(). This way the tty_port is automatically released as
soon as the tty is destroyed.
As a consequence the check for RFCOMM_RELEASE_ONHUP flag in the hangup()
method is now redundant. Instead we have to be careful with the reference
counting in the rfcomm_release_dev() function.
brcmfmac: use custom destructor callback for all netdevice interfaces
The destructor for net devices was set to free_netdev() to get rid
of it and the private data. The private data refers to a brcmf_if
instance, but indirectly it also refers to brcmf_cfg80211_vif which
holds the wdev. This is freed as well by using a new custom destructor
called brcmf_cfg80211_free_netdev().

brcmfmac: call brcmf_cfg80211_detach() after removal of interfaces
Instead of calling brcmf_cfg80211_detach() in brcmf_del_if() when
deleting the primary interface, call it in brcmf_detach() after
deleting all interfaces.
