nl80211/cfg80211: enable DFS for IBSS mode

2013-10-28T14:05:21+00:00

To use DFS in IBSS mode, userspace is required to react to radar events.
It can inform nl80211 that it is capable of doing so by adding a
NL80211_ATTR_HANDLE_DFS attribute when joining the IBSS.

This attribute is supplied to let the kernelspace know that the
userspace application can and will handle radar events, e.g. by
intiating channel switches to a valid channel. DFS channels may
only be used if this attribute is supplied and the driver supports
it. Driver support will be checked even if a channel without DFS
will be initially joined, as a DFS channel may be chosen later.

cfg80211: vlan priority handling in WMM

2013-10-02T09:04:33+00:00

If the VLAN tci is set in skb->vlan_tci use the
priority field to determine the WMM priority.

cfg80211/mac80211: get mandatory rates based on scan width

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

Mandatory rates for 5 and 10 MHz are different from the rates used for
20 MHz in 2.4 GHz mode, as they use OFDM only.

cfg80211: remove some locked wrappers from sme API

2013-05-24T22:02:22+00:00

By making all the API functions require wdev locking we
can clean up the API a bit, getting rid of the locking
version of each function. This also decreases the size
of cfg80211 by a small amount.

cfg80211: vastly simplify locking

2013-05-24T22:02:15+00:00

Virtually all code paths in cfg80211 already (need to) hold
the RTNL. As such, there's little point in having another
four mutexes for various parts of the code, they just cause
lock ordering issues (and much of the time, the RTNL and a
few of the others need thus be held.)

Simplify all this by getting rid of the extra four mutexes
and just use the RTNL throughout. Only a few code changes
were needed to do this and we can get rid of a work struct
for bonus points.

cfg80211: invert P2P-Device vs. netdev check ordering

2013-04-22T13:31:55+00:00

In cfg80211_can_use_iftype_chan(), check for P2P Device
first, and then for netdevs. This doesn't really change
anything but makes the code a bit easier to read since
it may not be obvious for everyone at first that a P2P
device has no netdev.

cfg80211: add ieee80211_operating_class_to_band

2013-04-16T13:29:43+00:00

This function converts a (global only!) operating
class to an internal band identifier. This will
be needed for extended channel switch support.
