If the beacon frames are generated by the host system (i.e., not in
hardware/firmware), the low-level driver uses this function to receive
the next beacon frame from the 802.11 code. The low-level is responsible
for calling this function before beacon data is needed (e.g., based on
hardware interrupt). Returned skb is used only once and low-level driver
is responsible for freeing it.
