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.

The issue was apparently introduced in git commit
eecc4800.

This is needed for drivers that need to know when the interface
is IF_OPER_UP (e.g. wl12xx), and block notifiers can't be used
(e.g. because the interface is already IF_OPER_UP, like after

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.

This patch adds a new field (dst_type) to the struct hci_conn which
holds the type of the destination address (bdaddr_t dst). This
approach is needed in order to use the struct hci_conn as an
abstraction of LE connections in HCI Layer. For non-LE this field
is ignored.
