cfg80211: add flags to cfg80211_rx_mgmt()

2013-08-23T14:06:03+00:00

Add flags intended to report various auxiliary information
and introduce the NL80211_RXMGMT_FLAG_ANSWERED flag to report
that the frame was already answered by the device.

nl80211/cfg80211: add channel switch command

2013-08-01T16:30:28+00:00

To allow channel switch announcements within beacons, add
the channel switch command to nl80211/cfg80211. This is
implementation is intended for AP and (later) IBSS mode.

nl80211: add scan width to bss and scan request structs

2013-07-16T06:58:01+00:00

To allow scanning and working with 5 MHz and 10 MHz BSS, extend the
inform bss commands and add wrappers to take 5 and 10 MHz bss into
account.

cfg80211/nl80211: Add packet coalesce support

2013-07-16T06:58:00+00:00

In most cases, host that receives IPv4 and IPv6 multicast/broadcast
packets does not do anything with these packets. Therefore the
reception of these unwanted packets causes unnecessary processing
and power consumption.

Packet coalesce feature helps to reduce number of received
interrupts to host by buffering these packets in firmware/hardware
for some predefined time. Received interrupt will be generated when
one of the following events occur.
a) Expiration of hardware timer whose expiration time is set to
maximum coalescing delay of matching coalesce rule.
b) Coalescing buffer in hardware reaches it's limit.
c) Packet doesn't match any of the configured coalesce rules.

This patch adds set/get configuration support for packet coalesce.
User needs to configure following parameters for creating a coalesce
rule.
a) Maximum coalescing delay
b) List of packet patterns which needs to be matched
c) Condition for coalescence. pattern 'match' or 'no match'
Multiple such rules can be created.

This feature needs to be advertised during driver initialization.
Drivers are supposed to do required firmware/hardware settings based
on user configuration.

cfg80211/nl80211: rename packet pattern related structures and enums

2013-07-16T06:57:55+00:00

Currently packet patterns and it's enum/structures are used only
for WoWLAN feature. As we intend to reuse them for new feature
packet coalesce, they are renamed in this patch.

Older names are kept for backward compatibility purpose.

{nl,cfg}80211: make peer link expiration time configurable

2013-06-11T12:16:29+00:00

If a STA has a peer that it hasn't seen any tx activity
from for a certain length of time, the peer link is
expired. This means the inactive STA is removed from the
list of peers and that STA is not considered a peer again
unless it re-peers.  Previously, this inactivity time was
always 30 minutes.  Now, add it to the mesh configuration
and allow it to be configured.  Retain 30 minutes as a
default value.

cfg80211: support an active monitor interface flag

2013-05-29T07:11:44+00:00

An active monitor interface is one that is used for communication (via
injection). It is expected to ACK incoming unicast packets. This is
useful for running various 802.11 testing utilities that associate to an
AP via injection and manage the state in user space.

cfg80211: Allow TDLS peer AID to be configured for VHT

2013-05-24T20:36:28+00:00

VHT uses peer AID in the PARTIAL_AID field in TDLS frames. The current
design for TDLS is to first add a dummy STA entry before completing TDLS
Setup and then update information on this STA entry based on what was
received from the peer during the setup exchange.

In theory, this could use NL80211_ATTR_STA_AID to set the peer AID just
like this is used in AP mode to set the AID of an association station.
However, existing cfg80211 validation rules prevent this attribute from
being used with set_station operation. To avoid interoperability issues
between different kernel and user space version combinations, introduce
a new nl80211 attribute for the purpose of setting TDLS peer AID. This
attribute can be used in both the new_station and set_station
operations. It is not supposed to be allowed to change the AID value
during the lifetime of the STA entry, but that validation is left for
drivers to do in the change_station callback.
