Thank you for your reply. I will ask another question... When debugging from "ath10k HTT", I usually see ADDBA requests coming when "associated" is finish. But very rarely, after "associated" completion, I could see the following behavior. Associated -> ADDBA -> DELBA -> ADDBA -> DELBA Is this normal case? Thanks. ----- Kim Kwang Min Mobile +82 010-5521-6393 Mail gwondori@nimbus.kr -----Original Message----- From: "Ben Greear" To: "Shajakhan, Mohammed Shafi (Mohammed Shafi)"; "ath10k@lists.infradead.org"; "KwangMin Kim"; Cc: "gwondori@nimbus.kr"; Sent: 2017-02-21 (화) 02:50:44 Subject: Re: who care of addba/delba in ath10k?

I think that ath10k's addba / delba is doing firmware. Is this right? And I have another question. If wmm is on, should TID '0' in agg_status (debugfs on mac80211) always be on?
