When the address translation for rx frames are done in fw/hw, it is very important to have an explicit link information reported for every rx frame to mac80211. Per-link processing includes stats update, GTK/IGTK/BIGTK retrieval and so on. This patch set only tries to use the link at the top level APIs, deep rx handlers are yet to be changed to use the respective link accordingly. This series is prepared on top of the latest mld branch.
