cfg80211: use reassociation when possible
With the move of everything related to the SME from mac80211 to cfg80211, we lost the ability to send reassociation frames. This adds them back, but only for wireless extensions. With the userspace SME, it shall control assoc vs. reassoc (it already can do so with the nl80211 interface). I haven't touched the connect() implementation, so it is not possible to reassociate with the nl80211 connect primitive. I think that should be done with the NL80211_CMD_ROAM command, but we'll have to see how that can be handled in the future, especially with fullmac chips. This patch addresses only the immediate regression we had in mac80211, which previously sent reassoc. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.
