[PATCH 0/2 v3] mac80211/cfg80211: add support for userspace to handle auth frames on adhoc ifaces

[Will Hawkins <hawkinsw@opentechinstitute.org>]

Hello!

I am sending along 2 patches to add support for user space applications
to register for authentication frames on adhoc interfaces. These are
revisions to a previous patch that I submitted to accomplish the same
thing.

Patch 1/2 adds a cfg80211_mgmt_reg_match function to cfg80211 to
check whether a user space application is registered for a particular
type of management frame rx'd on a particular device. The new function
is very similar to cfg80211_rx_mgmt. cfg80211_rx_mgmt could not be
reused because of its side-effect of transmitting the "query" frames to
the registered userspace applications. This patch modifies the
documentation for cfg80211_rx_mgmt to reflect that.

Patch 2/2 sets the necessary flags to allow userspace
applications to register for authentication frames on adhoc interfaces.
It also adds a check to make sure that "open" authentication frames are
not sent when a user space application is registered for authentication
frames.

As I've said before, I'm still new to this process so I look forward to
your feedback on improving.

Will
