Hi all, I am trying to "completely" disable RTS/CTS.
* Case 1: Using iw/iwconfig when I set the sender's RTS threshold to a very high value (RTS thr=10000 B), I expect that no RTS should be sent. However, it seems that this threshold is not being honored and I can sniff large number of RTS/CTS frames. I verified that no A-MSDU is exceeding 10000 B. * Case 2: Interestingly, when I set the sender's RTS threshold to off (RTS thr:off), compared to case #1 much less number of RTS/CTS frames are seen and throughput is seen to improve. But I can still see RTS/CTS frames being sent. * Since the channel is clear and much isolated, and there is just one AP and one STA, there is negligible chance of other factors playing any role. * There is one change though that I have disabled dynamic bandwidth i.e. ar->wmi.pdev_param->dynamic_bw set zero in mac.c. I believe this is likely not an issue as similar RTS/CTS behavior is seen even with dynamic_bw set to 1 (there are no heterogeneous channel widths in the network in any case). * Another thing I noticed is that the RTS/CTS protection mode if set, it is set to CTS-to-self, rather than "RTS/CTS" i.e. ar->wmi.vdev_param->protection_mode in mac.c is either set to 1 or 0 (depending upon use_cts_prot), but not 2. This probably seems not helpful in hidden node scenarios as the CTS frame is unicasted instead broadcasting. I would appreciate any pointers on completely disabling RTS/CTS as well as the ability to choose between complete RTS/CTS versus CTS-to-self whenever RTS/CTS is enabled.
