When changing the alternate setting for the ISOC endpoints, use the
hci_conn_num() helper function to count currently established SCO
and eSCO connections and store the the value. This avoids direct
access to the connection hash.
In addition use the stored value instead accessing the connection
hash over and over again.

When checking for the current number of LE connections, use
hci_conn_num() function instead of a full blown lookup within
the connection hash or direct access of the counters.
In the case of re-enabling advertising, it is more useful to
check for any connection attempt or existing connection.

The Ralink DPO_RT5572_LinuxSTA_2.6.1.3_20121022
reference driver uses different RSSI threshold
and VGC adjustment values for the RT3572 and
RT3593 chipsets.
Update the rt2800_link_tuner function to use the
same values. Also change the comment in the function
to make it more generic.

In commit 3d81535ea5940446510a8a5cee1c6ad23c90c753
(rt2800: 5592: add chip specific vgc calculations)
the rt2800_link_tuner function has been modified to
adjust VGC level for the RT5592 chipset.
On the RT5592 chipset, the VGC level must be adjusted
only if rssi is greater than -65. However the current
code adjusts the VGC value by 0x10 regardless of the
actual chipset if the rssi value is between -80 and
-65.
Fix the broken behaviour by reordering the if-else
statements.

Pausing queue on flush make no sense since txdone procedure un-pause
queue. Before flush procedure we have to assure queue is stopped,
i.e. on receive path h/w RX is disabled, on transmit path queue is
disabled in mac80211. That conditions are true except one function:
rt2x00usb_watchdog_tx_dma(), so add stop/start queue there.
Note stop/start queue can be racy if we do this from multiple paths,
but currently we stop TX queues only on rt2x00lib_disable_radio(),
which also stop/sync watchdog, hance we have no race condition.

The rt2x00 driver uses 0x22 as a default VGC value
in VGC adjustment for the RT3572 chipset. In the
Ralink DPO_RT5572_LinuxSTA_2.6.1.3_20121022 driver,
this value is only used for initialization. During
VGC adjustment, the reference driver uses different
values.
Update the 'rt2800_get_default_vgc' function to
synchronize the values with the reference driver.
Also add the missing AGC initialization code into
the 'rt2800_config_channel' function.

According to the DPO_RT5572_LinuxSTA_2.6.1.3_20121022
reference driver, programming of the 'BBP 66' register
on the RT3572 and RT3593 chipsets must be done via the
'rt2800_bbp_write_with_rx_chain' function. This ensures
that value is correclty set for all RX chains.

The comments are indicating that the TXMIXER_GAIN_BG
and TXMIXED_GAIN_A entries are overlapping with the
RSSI_BG2 and RSSI_A2 entries in the extended EEPROM
map. This is not correct, because the upper byte of
the RSSI_BG2 and RSSI_A2 entries are reserved. There
are no TX mixer gain values are stored at all in the
extended EEPROM.
Remove the initialization of these entries from the
extended EEPROM map to reflect this.

such a card on a router connected to some BCM63XX SoC via PCIe. There
are cards out there with the same PCI id and a BCM4311, which is a pre
ieee80211n chip only supporting ieee80211a, these are still not
supported by b43 and not detected by ssb.

Currently driver name is wrong. PCI device address is visible at
/proc/interrupts instead of the name:
43: 124 0 0 0 PCI-MSI-edge rtsx_pci
44: 384 0 0 0 PCI-MSI-edge snd_hda_intel
45: 25096 0 0 0 PCI-MSI-edge 0000:01:00.0
^^^^^^^^^^^^
So, pass the right name. rt2x00_ops->name contains KBUILD_MODNAME
and good for that, so pass it.
Handler names will be "rt2500pci", "rt2500pci" etc.

The l2cap_recv_frame function is expected to take ownership and
eventually free the skb passed to it. We need to ensure that the
conn->rx_skb pointer is no longer reachable when calling
l2cap_recv_frame so that no other function, such as l2cap_conn_del, may
think that it can free conn->rx_skb.
An actual situation when this can happen is when smp_sig_channel (called
from l2cap_recv_frame) fails and l2cap_conn_del gets called as a
consequence. The l2cap_conn_del function would then try to free
conn->rx_skb, but as the same skb was just passed to smp_sig_channel and
freed we get a double-free.

The support for Bluetooth High Speed can only be enabled on controllers
where also Secure Simple Pairing has been enabled. Trying to enable
high speed when SSP is disabled will result into an error. Disabling
SSP will at the same time disable high speed as well.
It is required to enforce this dependency on SSP since high speed
support is only defined for authenticated, unauthenticated and
debug link keys. These link key types require SSP.

We only (re)enable advertising when LE is disconnected. Trying to enable

change the flag but not do anything else (until the connection gets

The management interface only operates on BR/EDR controllers. The check
for the power down notification is a bit intermixed with the check if
controller auto power off is active. Since there are more than just
BR/EDR controllers supported, make this check explicit since the auto
power off check also applies to AMP controllers and it has to happen
in this exact order. Otherwise the bit will not be cleared.

Even AMP controllers should be powered off after the setup phase. It
is not a good idea to keep AMP controllers powered on all the time
if they are not in use.
Power on of the AMP controller can either be done manually via
command line commands or directly via A2MP. Especially since there
is an indication in A2MP for powered down controllers that can
be activated.
