That did not work. 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.
