Hi, Javier and Thomas > Yes, but you are assuming that Thomas' patch does successfully filter > out the RA mismatch frames. > Is it possible for you to paste the frame dumps of the duplicated > frames? Are they identical frames (same DA, SA, TA, RA and mesh > seqnum)? Do they have different TA? Something else? Ok, I have put some log information to check for the RA, TA, DA, SA and also seqnum,
I have doing a Ping from 11th node to 1st node for about an hour. Ping results are as follow: 355556 packets transmitted, 349013 received, 1% packet loss, time 4166648ms rtt min/avg/max/mdev = 2.717/11.554/3160.335/35.995 ms, pipe 10 Here are amount of duplicate unicast frame detected.

Just show a few records since most of them have similar pattern. SA and DA are both MAC addresses from the Ping nodes. Based on the observation, the duplicate frame [2] has the same sequence number, RA, DA and SA, but TA is different. So it should be due to the path refresh since the detected duplicate frame is coming from different TA. --- Chun-Yeow P.S: Change the topic subject since it may not due to the same problem reported by MingAnn _______________________________________________ Devel mailing list [email protected] http://lists.open80211s.org/cgi-bin/mailman/listinfo/devel
