| 5057 | * Function: |
| 5058 | * This is LIM's very own "TX MGMT frame complete" completion routine. |
| 5059 | * |
| 5060 | * Logic: |
| 5061 | * LIM wants to send a MGMT frame (broadcast or unicast) |
| 5062 | * LIM allocates memory using palPktAlloc( ..., **pData, **pPacket ) |
| 5063 | * LIM transmits the MGMT frame using the API: |
| 5064 | * halTxFrame( ... pPacket, ..., (void *) limTxComplete, pData ) |
| 5065 | * HDD, via halTxFrame/DXE, "transfers" the packet over to BMU |
| 5066 | * HDD, if it determines that a TX completion routine (in this case |
| 5067 | * limTxComplete) has been provided, will invoke this callback |
| 5068 | * LIM will try to free the TX MGMT packet that was earlier allocated, in order |
| 5069 | * to send this MGMT frame, using the PAL API palPktFree( ... pData, pPacket ) |
| 5070 | * |
| 5071 | * Assumptions: |
| 5072 | * Presently, this is ONLY being used for MGMT frames/packets |
| 5073 | * TODO: |
| 5074 | * Would it do good for LIM to have some sort of "signature" validation to |
| 5075 | * ensure that the pData argument passed in was a buffer that was actually |
| 5076 | * allocated by LIM and/or is not corrupted? |
| 5077 | * |
| 5078 | * Note: FIXME and TODO |
| 5079 | * Looks like palPktFree() is interested in pPacket. But, when this completion |
| 5080 | * routine is called, only pData is made available to LIM!! |
| 5081 | * |
