The ZD1211 retry register is set to 2, which gives 4 retries. (It has four bits so you could ask for 2^15 retries. ;-) I cannot explain packets 4 to 9 -- this might be firmware behaviour, which we cannot control. However the d80211 developers discussed to implement such behaviour in the new d80211 stack. Does the 802.11 standard really care, what the payload is? What prevents me to send the same UDP packet three times? On the 802.11 layer it is a new packet, because it has a new sequence number.
