Tom Gundersen 6bab2e19c5 cfg80211: pass name_assign_type to rdev_add_virtual_intf()
This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.

Similar functionality was introduced for the rtnetlink core in
commit 5517750f05 ("net: rtnetlink - make create_link take name_assign_type")

Dedy Lansky 6eb1813764 cfg80211: add bss_type and privacy arguments in cfg80211_get_bss()
802.11ad adds new a network type (PBSS) and changes the capability
field interpretation for the DMG (60G) band.
The same 2 bits that were interpreted as "ESS" and "IBSS" before are
re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid
values are: "IBSS", "PBSS" (new) and "AP".

In order to get the BSS struct for the new PBSS networks, change the
cfg80211_get_bss() function to take a new enum ieee80211_bss_type
argument with the valid network types, as "capa_mask" and "capa_val"
no longer work correctly (the search must be band-aware now.)

The remaining bits in "capa_mask" and "capa_val" are used only for
privacy matching so replace those two with a privacy enum as well.

Johannes Berg b51f3beecf cfg80211: change bandwidth reporting to explicit field
For some reason, we made the bandwidth separate flags, which
is rather confusing - a single rate cannot have different
bandwidths at the same time.

Change this to no longer be flags but use a separate field
for the bandwidth ('bw') instead.

While at it, add support for 5 and 10 MHz rates - these are
reported as regular legacy rates with their real bitrate,
but tagged as 5/10 now to make it easier to distinguish them.

In the nl80211 API, the flags are preserved, but the code
now can also clearly only set a single one of the flags.

Johannes Berg 319090bf6c cfg80211: remove enum station_info_flags
This is really just duplicating the list of information that's
already available in the nl80211 attribute, so remove the list.
Two small changes are needed:
 * remove STATION_INFO_ASSOC_REQ_IES complete, but the length
   (assoc_req_ies_len) can be used instead
 * add NL80211_STA_INFO_RX_DROP_MISC which exists internally
   but not in nl80211 yet

This gets rid of the duplicate maintenance of the two lists.

Johannes Berg 4ed20bebf5 cfg80211: remove "channel" from survey names
All of the survey data is (currently) per channel anyway,

Avinash Patil dda9ddeb26 mwifiex: do not delete station entries in del_sta handler
A crash was observed while cfg80211 del_station handler is
called while stopping AP. This was happening because we were
deleting station list and Rx reorder table entries in del_sta
handler. While station entry is being deleted here, it may happen
that station deauth event from FW would also try to delete station
entry.

This patch fixes this crash by not deleting station entries in del_station
handler. Entry would be deleted while processing station deauth event; which
is triggered by del_station command to FW.

Avinash Patil 9927baa3c7 mwifiex: add auto TDLS support
This patch adds auto TDLS support to mwifiex.

Auto TDLS functionality works as follows:
1. Whenever userspace application has triggered TDLS connection with
any peer, driver would store this peer mac address details in its database.
2. After this driver whenever driver receives packet on direct link,
it would store rssi and timestamp in peer information.
3. Whenever a packet is to be transmitted to non-AP peer in station mode,
driver would check if TDLS link can be established by looking at peer RSSI
information. Driver would initiate TDLS setup in such cases.
4. Periodic timer is used for updating peer information.
5. Auto TDLS peer list & timer are cleared during disconnection or driver unload.

With scan channel gap when any station/AP is active, FW comes back
to connected channel for any pending data transfter after scanning each
channel.
We set scan channel gap TLV to FW in scan command when any of the
interface is active. This enables scan channel gap in FW.
Also when scan channel gap is enabled, we would scan maximum channels
allowed by FW.

Scan channel gap is supported only on FW with V15 FW API.

It was observed that station would sent probe request even when
scan type has been set as passive during iw scan.
This was happening because driver sets passive scan type only
when channel has IEEE80211_CHAN_NO_IR flag set.
Along with this, add condition to check if no ssids are specified in
scan request so as to mark such scan request passive.
