Johannes Berg says:

====================
Various fixes across the tree, the shortlog basically says it all:

  cfg80211: fix cfg80211_beacon_dup
  -> old bug in this code

  cfg80211: clear wep keys after disconnection
  -> certain ways of disconnecting left the keys

  mac80211: round IEEE80211_TX_STATUS_HEADROOM up to multiple of 4
  -> alignment issues with using 14 bytes

  mac80211: Do not disconnect on invalid operating class
  -> if the AP has a bogus operating class, let it be

  mac80211: Fix sending ADDBA response for an ongoing session
  -> don't send the same frame twice

  cfg80211: use only 1Mbps for basic rates in mesh
  -> interop issue with old versions of our code

  mac80211_hwsim: don't use WQ_MEM_RECLAIM
  -> it causes splats because it flushes work on a non-reclaim WQ

  regulatory: add NUL to request alpha2
  -> nla_put_string() issue from Kees

  mac80211: mesh: fix wrong mesh TTL offset calculation
  -> protocol issue

  mac80211: fix a possible leak of station stats
  -> error path might leak memory

  mac80211: fix calling sleeping function in atomic context
  -> percpu allocations need to be made with gfp flags
