| 5031 | * Function: |
| 5032 | * This is LIM's very own "TX MGMT frame complete" completion routine. |
| 5033 | * |
| 5034 | * Logic: |
| 5035 | * LIM wants to send a MGMT frame (broadcast or unicast) |
| 5036 | * LIM allocates memory using palPktAlloc( ..., **pData, **pPacket ) |
| 5037 | * LIM transmits the MGMT frame using the API: |
| 5038 | * halTxFrame( ... pPacket, ..., (void *) limTxComplete, pData ) |
| 5039 | * HDD, via halTxFrame/DXE, "transfers" the packet over to BMU |
| 5040 | * HDD, if it determines that a TX completion routine (in this case |
| 5041 | * limTxComplete) has been provided, will invoke this callback |
| 5042 | * LIM will try to free the TX MGMT packet that was earlier allocated, in order |
| 5043 | * to send this MGMT frame, using the PAL API palPktFree( ... pData, pPacket ) |
| 5044 | * |
| 5045 | * Assumptions: |
| 5046 | * Presently, this is ONLY being used for MGMT frames/packets |
| 5047 | * TODO: |
| 5048 | * Would it do good for LIM to have some sort of "signature" validation to |
| 5049 | * ensure that the pData argument passed in was a buffer that was actually |
| 5050 | * allocated by LIM and/or is not corrupted? |
| 5051 | * |
| 5052 | * Note: FIXME and TODO |
| 5053 | * Looks like palPktFree() is interested in pPacket. But, when this completion |
| 5054 | * routine is called, only pData is made available to LIM!! |
| 5055 | * |
