net: wireless: bcmdhd: Remove WIPHY_FLAG_SUPPORTS_FW_ROAM flag

If driver advertises FW_ROAM, the supplicant wouldn't send
the BSSID & Freq in the connect command allowing the driver
to choose the AP to connect to. But unless we support ROAM_CACHE
in firware this will delay the ASSOC as the FW need to do a full
scan before attempting to connect.

cfg80211/nl80211: support GTK rekey offload

In certain circumstances, like WoWLAN scenarios,
devices may implement (partial) GTK rekeying on
the device to avoid waking up the host for it.

In order to successfully go through GTK rekeying,
the KEK, KCK and the replay counter are required.

Add API to let the supplicant hand the parameters
to the driver which may store it for future GTK
rekey operations.

Note that, of course, if GTK rekeying is done by
the device, the EAP frame must not be passed up
to userspace, instead a rekey event needs to be
sent to let userspace update its replay counter.

cfg80211/nl80211: Add PMKSA caching candidate event

When the driver (or most likely firmware) decides which AP to use
for roaming based on internal scan result processing, user space
needs to be notified of PMKSA caching candidates to allow RSN
pre-authentication to be used.

nl80211: support sending TDLS commands/frames

Add support for sending high-level TDLS commands and TDLS frames via
NL80211_CMD_TDLS_OPER and NL80211_CMD_TDLS_MGMT, respectively. Add
appropriate cfg80211 callbacks for lower level drivers.

Add wiphy capability flags for TDLS support and advertise them via
nl80211.

nl80211: advertise GTK rekey support, new triggers

Since we now have the necessary API in place to support
GTK rekeying, applications will need to know whether it
is supported by a device. Add a pseudo-trigger that is
used only to advertise that capability. Also, add some
new triggers that match what iwlagn devices can do.

nl80211: advertise device AP SME

Add the ability to advertise that the device
contains the AP SME and what features it can
support. There are currently no features in
the bitmap -- probe response offload will be
advertised by a few patches Arik is working
on now (who took over from Guy Eilam) and a
device with AP SME will typically implement
and require response offload.

nl80211: allow subscribing to unexpected class3 frames

To implement AP mode without monitor interfaces we
need to be able to send a deauth to stations that
send frames without being associated. Enable this
by adding a new nl80211 event for such frames that
an application can subscribe to.
