I did change ieee80211_monitor_start_xmit() in mac80211 tx.c where it sets the info->flags from: info->flags = IEEE80211_TX_CTL_REQ_TX_STATUS | IEEE80211_TX_CTL_INJECTED; to the following: info->flags = IEEE80211_TX_CTL_REQ_TX_STATUS | IEEE80211_TX_CTL_NO_ACK IEEE80211_TX_CTL_INJECTED; and that got rid of the retries. When injecting. This is because the setting of the IEEE80211_TX_CTL_NO_ACK flag in ieee80211_monitor_start_xmit(), allows the ath9k ath_tx_fill_desc() to check the flags and set ATH9K_TXDESC_NOACK properly. -Clyde > Okay, thank you for the information. > > -Clyde > On 03/15/2013 04:28 PM, Adrian Chadd wrote: >> You need to ensure that: >> >> * you don't request an ACK if you don't want one; >> * you set the hardware retry count to 1 >> >> >> >> Adrian >> >> >> On 15 March 2013 10:54, C.
