      cfg80211: send events when devices are added/removed · 3bb20556
      Johannes Berg authored
      We're currently sending NEW_WIPHY events for renames (which
      is a bit odd, but now can't be changed), but also send them
      for really new devices that register.
      
      Also send DEL_WIPHY events when a device is removed, the
      event ID for this was already reserved.

      mac80211: fix virtual monitor interface addition · 34171dc0
      Emmanuel Grumbach authored
      Since the commit below, cfg80211_chandef_dfs_required()
      will warn if it gets a an NL80211_IFTYPE_UNSPECIFIED iftype
      as explicitely written in the commit log.
      When an virtual monitor interface is added, its type is set
      in ieee80211_sub_if_data.vif.type, but not in
      ieee80211_sub_if_data.wdev.iftype which is passed to
      cfg80211_chandef_dfs_required() hence resulting in the
      following warning:

      mac80211: add a single-transaction driver op to switch contexts · 1a5f0c13
      Luciano Coelho authored
      In some cases, when the driver is already using all the channel
      contexts it can handle at once, we have to do an in-place switch
      (ie. we cannot afford using an extra context temporarily for the
      transaction).  But some drivers may not support switching the channel
      context assigned to a vif on the fly (ie. without unassigning and
      assigning it) while others may only work if the context is changed on
      the fly, without unassigning it first.
      
      To allow these different scenarios, add a new driver operation that
      let's the driver decide how to handle an in-place switch.
