Yes.

I investigate the issue a bit further by modifying the ibss.c and also mac.c

Case 1:
Create, Associate (Legacy Rate), Disassociate, Delete, Create,
Associate (HT Rate)
--- TxRate always stuck at 6Mbps

Case 2:
Create, Associate (Legacy Rate), Disassociate, Delete, Create,
Associate (Legacy Rate)
--- Rate control works with TxRate going out to 54Mbps even after
delete and associate back the STA.

Case 3:
Create, Associate (HT Rate)
--- TxRate always stuck at 6Mbps

So it seems that the rate control is not working in the FW whenever
you configure the HT mode for the adhoc mode.

Any idea how to solve this?
