rS306590: net80211: add one-vap version of ieee80211_iterate_nodes()
Summary
  • Add a counter into 'struct ieee80211_node_table' to save current number of allocated nodes.
    • This change allows to remove possible memory overheads / array overflow failures in ieee80211_iterate_nodes().
  • Add ieee80211_iterate_nodes_vap() function; unlike non-vap version, it iterates on nodes for specified vap only.

Also:

  • Remove ieee80211_iterate_nt(); it is not used by drivers / net80211 outside ieee80211_iterate_nodes() function + cannot be separated due to structural changes in code.
  • Since this change increases size of ieee80211_node_table structure, this change will break KBI.
Test Plan

Tested with wpi(4) in STA mode.
