| 4839 | * |
| 4840 | * Logic: |
| 4841 | * LIM wants to send a MGMT frame (broadcast or unicast) |
| 4842 | * LIM allocates memory using cds_packet_alloc( ..., **pData, **pPacket ) |
| 4843 | * LIM transmits the MGMT frame using the API: |
| 4844 | * wma_tx_frame( ... pPacket, ..., (void *) lim_tx_complete, pData ) |
| 4845 | * HDD, via wma_tx_frame/DXE, "transfers" the packet over to BMU |
| 4846 | * HDD, if it determines that a TX completion routine (in this case |
| 4847 | * lim_tx_complete) has been provided, will invoke this callback |
| 4848 | * LIM will try to free the TX MGMT packet that was earlier allocated, in order |
| 4849 | * to send this MGMT frame, using the PAL API cds_packet_free( ... pData, pPacket ) |
| 4850 | * |
| 4851 | * Assumptions: |
| 4852 | * Presently, this is ONLY being used for MGMT frames/packets |
| 4853 | * TODO: |
| 4854 | * Would it do good for LIM to have some sort of "signature" validation to |
| 4855 | * ensure that the pData argument passed in was a buffer that was actually |
| 4856 | * allocated by LIM and/or is not corrupted? |
| 4857 | * |
| 4858 | * Note: FIXME and TODO |
| 4859 | * Looks like cds_packet_free() is interested in pPacket. But, when this completion |
| 4860 | * routine is called, only pData is made available to LIM!! |
