The connection status is to be kept per virtual interface and
the scanning status is for device. So they need to be separated
for multiple interface support.

This checks the status that will soon be moved to virtual

brcmf_cfg80211_vif as parameter instead.

The profile information applies to an interface so each virtual
interface needs it. So it is removed from brcmf_cfg80211_info
and added to brcmf_cfg80211_vif structure.

The functions for communicating were given the net_device only because
its private data contained struct brcmf_if object. However, not all
firmware related interfaces will be associated with a net_device. To
accomodate provisioning firmware for such interfaces the struct
brcmf_if object will be passed to the fwil functions.

The firmware interface has functions to send bsscfg specific commands
to the device. These functions currently have a bssidx parameter, but
that same information is stored in struct brcmf_if, which is in the

When the firmware notifies the driver about adding a new interface
it also provides an index for the bss associated with this interface.
This index will be needed for upcoming features like peer-to-peer.
By adding this index in struct brcmf_if it is easy to obtain as this
will be associated with the net_device private data.

carl9170_handle_mpdu is the final part of the
rx path of the driver. It splits the raw data
streams from the device into skb packets and
passes them on to mac80211. As a result of
continuous updates, it grew over the years when
new code was added by the following commits:
- report A-MPDU status
- fix HT peer BA session corruption
- A-MPDU frame type filter
- ...
This patch splits the routine into two stages.
The first stage only deals with the details
about extracting and verifying the data from
the incoming stream. Whereas the second stage
packs it into skbs and passes it on to mac80211.

This reverts commit 34202e28fe7fc8551313f9a035a8857db83de757
We made "34202ee.." because we didn't support custom regulatory rules
at that time. But now we use our own custom regulatory rules, so it
needs to be changed back.
Also, chan->max_power calculations in cfg80211 were broken. Hence we
started using chan->max_reg_power. Now it has got fixed in
following commit.

When the BT connection is initiated by headset, it's possible that headset
requests to make one A2DP and one Voice connection over the same link.
BT firmware will send a new profile A2DP_Voice in this case. So WLAN

While resuming from S3, BT host issues HCI reset command and it
causes BT firmware to busy with security key calculation. At this
movement, WLAN detects MCI hardware error of MCI_CONT_INFO_TIMEOUT
and then it starts the recovery sequence repeatedly. Too many
recovery sequences would exhaust the BT kernel message pool. This
patch imposes a duration between consecutive BT recovery procedure.
Thus it solves BT firmware panic issue reported in AR9565.

The simulataneous transmission of both WLAN and BT might cause
increase in power levels. To avoid regulatory violation, WLAN tx
power will be adjusted according to BT power index based on avaliability
of BT scheduling messages. WLAN tx power reduction might affect its
performance. So WLAN tx power is only be lowered when the signal strength
is good enough. Otherwise concurrent tx will be disabled and WLAN uses
it default power levels. Also concurrent tx is disabled whenever WLAN is
moving to off-channel which might be used by BT.

This feature enables both WLAN and BT can transmit simultaneously
by setting WLAN and BT to equal priorities. Whenever both are

combined power exceeds threshold, BT transmission will be held off.

(from STOMP_LOW) to provide more bandwidth for BT FTP profile.
WLAN's idleness can be estimated by taking into account of the

Several people have complained about an unusual

In siffer mode, the hardware generates spurious
ACK frames for every received frame... even
broadcasts.
The reason for this malfunction is unknown:
<http://marc.info/?l=linux-wireless&m=134517238506033>
But there's a workaround: Instead of the special
sniffer mode, the hardware will be put into
station mode and all rx filters are disabled.
