mac80211: move "bufferable MMPDU" check to fix AP mode scan

2013-12-16T20:44:05+00:00

The check needs to apply to both multicast and unicast packets,
otherwise probe requests on AP mode scans are sent through the multicast
buffer queue, which adds long delays (often longer than the scanning
interval).

{nl,cfg,mac}80211: implement mesh channel switch userspace API

2013-10-28T14:05:30+00:00

Implement the required procedures for mesh channel switching as defined
in the IEEE Std 802.11-2012 section 10.9.8.4.3 and also handle the CSA
and MCSP elements as followed:
 * Add the function for updating the beacon and probe response frames
   with CSA and MCSP elements during the period of switching to the new
   channel. Both CSA and MCSP elements must be included in beacon and
   probe response frames until the intended channel switch time.
 * The ifmsh->csa_settings is set to NULL and the CSA and MCSP elements
   will then be removed from the beacon or probe response frames once the
   new channel is switched to.

mac80211: add ieee80211_tx_prepare_skb() helper function

2013-10-28T14:05:27+00:00

This can be used by a driver to prepare skbs for transmission, which were
obtained via functions such as ieee80211_probereq_get or
ieee80211_nullfunc_get.

This is useful for drivers that want to send those frames directly, but
need rate control information to be prepared first.

mac80211: use sta_info_get_bss() for nl80211 tx and client probing

2013-09-30T09:30:57+00:00

This allows calls for clients in AP_VLANs (e.g. for 4-addr) to succeed

mac80211: add support for CSA in IBSS mode

2013-09-26T11:27:14+00:00

This function adds the channel switch announcement implementation for the
IBSS code. It is triggered by userspace (mac80211/cfg) or by external
channel switch announcement, which have to be adopted. Both CSAs in
beacons and action frames are supported. As for AP mode, the channel
switch is applied after some time. However in IBSS mode, the channel
switch IEs are generated in the kernel.

mac80211: assign seqnums for group QoS frames

2013-08-23T13:43:38+00:00

According to 802.11-2012 9.3.2.10, paragraph 4, QoS
data frames with a group address in the Address 1 field
have sequence numbers allocated from the same counter
as non-QoS data and management frames.  Without this
flag, some drivers may not assign sequence numbers, and
in rare cases frames might get dropped.  Set the control
flag accordingly.

mac80211: add control port protocol TX control flag

2013-08-12T12:09:29+00:00

A lot of drivers check the frame protocol for ETH_P_PAE,
for various reasons (like making those more reliable).
Add a new flags bitmap to the TX control info and a new
flag indicating the control port protocol is in use to
let all drivers also apply such logic to other control
port protocols, should they be configured.

Also use the new flag in the iwlwifi drivers.
