cfg80211: introduce scan IE limit attribute
This patch introduces a new attribute for a wiphy that tells userspace how long the information elements added to a probe request frame can be at most. It also updates the at76 to advertise that it cannot support that, and, for now until I can fix that, iwlwifi too. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
