In the brcm80211 driver we disable the 80211 core when the driver is
'down'. The bcma_core_disable() function exactly does the same as
our implementation so exporting this function makes sense.

1) Avoid global adapter pointer usage
   a) in sdio.c by moving some code from mwifiex_cleanup_module() to
      mwifiex_sdio_remove().
   b) in main.c by passing an extra parameter to few functions.
2) Add new variable "user_rmmod" to identify if mwifiex_sdio_remove()
   callback function is called in card removal or rmmod context. These
   code changes are adapted from Libertas driver.
3) Remove unnecessary NULL pointer check for "func" pointer in
   mwifiex_sdio_remove().

At http://dev.laptop.org/ticket/10748 we are seeing a case of the
libertas firmware randomly stopping responding to commands after
resume. Careful monitoring of communications indicates a firmware or
hardware bug, which has been reported to Marvell.

Work around this issue by adding a reset_card method; this is
automatically called when command timeouts are detected and provides an
instant recovery to this situation.

Function ieee80211_reconfig in net/mac80211/util.c contains label wake_up
which is defined unconditionally, but only used with CONFIG_PM. Gcc
warns about this when CONFIG_PM is not defined.

This patch makes the label's definition dependent on CONFIG_PM too,
eliminating the warning.

Add BT_POWER socket option used to control the power
characteristics of the underlying ACL link. When the remote end
has put the link in sniff mode and the host stack wants to send
data we need need to explicitly exit sniff mode to work well with
certain devices (For example, A2DP on Plantronics Voyager 855).
However, this causes problems with HID devices.

Hence, moving into active mode when sending data, irrespective
of who set the sniff mode has been made as a socket option. By
default, we will move into active mode. HID devices can set the
L2CAP socket option to prevent this from happening.

Currently, this has been implemented for L2CAP sockets. This has been
tested with incoming and outgoing L2CAP sockets for HID and A2DP.

Based on discussions on linux-bluetooth and patches submitted by
Andrei Emeltchenko.

holds the type of the destination address (bdaddr_t dst). This
approach is needed in order to use the struct hci_conn as an

is ignored.
