[Madwifi-devel] How to obtain the packet which the NIC is currently retransmitting?

[David F. <df...@ac...>]

Hi all,
is there a way to know which is the packet that the wireless card is 
currently retransmitting?
i.e. is it possible to obtain, from the ath_uapsd_processtriggers(...) 
routine (that is, when receiving a packet), the packet which the 
wireless card is currently retransmitting (because no ACK is received 
during past retransmissions)?

Example:
1. NIC sends packet P1
2. NIC receives ACK
3. NIC sends packet P2
4. NIC sends packet P2
5. NIC sends packet P2
6. NIC receives packet P3
<-- At this moment, from the ath_uapsd_processtriggers(...) routine or 
similar, could I obtain packet P2? i.e. could I know that packet P2 is 
the current packet being retransmitted?-->
7. NIC sends packet P2
8. NIC sends packet P2
9. NIC receives ACK

Thank you very much!
david
