[Click] I could not get any packet from the second output of ACKRetrySender and ACKResponder

[Seng Molika]

Dear all,

I would like to ask for helps to my two questions.
  1- I am not sure my Classifier to filter 'ack', is it correct?
  2- I could not see any output from ACKRetrySender and ACKResponder. What
is the problem do I have in my click file?

The first PC, I am running hostap to make it as access point and its
Ethernet Address: 74:EA:3A:8F:38:18.
The second PC worked as the station and its Ethernet Address: C0 18 85 17
08 BC.

Click file 'test_ackRetrySender.click' run on PC_ap, and
Click file 'test_ackResponder.click' run on PC_station.

And the following are my click files which I am testing on 2 computer in
user level mode.

========= test_ackRetrySender.click ===========

>From the output file of ap.records and station.records, I could see that I
could not recieve any packets from output 1 of ACKRetrySender and
ACKResponder at all.

Thank you in advance,
