This driver event was used separately for some Action frames, but all the driver wrappers converted to this from information that would have been enough to indicate an EVENT_RX_MGMT event. In addition, the received event was then converted back to a full IEEE 802.11 management frame for processing in most cases. This is unnecessary complexity, so get rid of the extra path and use EVENT_RX_MGMT for Action frames as well as other management frame subtypes. Signed-hostap: Jouni Malinen <j@w1.fi>
