 * LIM wants to send a MGMT frame (broadcast or unicast)
 * LIM allocates memory using cds_packet_alloc( ..., **pData, **pPacket )
 * LIM transmits the MGMT frame using the API:
 *  wma_tx_frame( ... pPacket, ..., (void *) lim_tx_complete, pData )
 * HDD, via wma_tx_frame/DXE, "transfers" the packet over to BMU
 * HDD, if it determines that a TX completion routine (in this case
 * lim_tx_complete) has been provided, will invoke this callback
 * LIM will try to free the TX MGMT packet that was earlier allocated, in order
 * to send this MGMT frame, using the PAL API cds_packet_free( ... pData, pPacket )
 *
 * Assumptions:
 * Presently, this is ONLY being used for MGMT frames/packets
 * TODO:
 * Would it do good for LIM to have some sort of "signature" validation to
 * ensure that the pData argument passed in was a buffer that was actually
 * allocated by LIM and/or is not corrupted?
 *
 * Note: FIXME and TODO
 * Looks like cds_packet_free() is interested in pPacket. But, when this completion
 * routine is called, only pData is made available to LIM!!
