Hi. I saw strange batman logs while testing a batman-adv mesh. Batman-adv module was continuously generating the same logs including a " Creating new originator: b0:c6:9b:80:01:43". But b0:c6:9b:80:01:43 never appears in the output of 'batctl o': admin@HND-Mesh:~# batctl o [B.A.T.M.A.N. adv 2012.0.0, MainIF/MAC: wlan0/b0:c6:9b:80:01:5b (bat0)] Originator last-seen (#/255) Nexthop [outgoingIF]: Potential nexthops ... b0:c6:9b:80:01:5c 0.010s (255) b0:c6:9b:80:01:5c [ wlan0]: b0:c6:9b:80:01:5f (209) b0:c6:9b:80:01:6b (231) b0:c6:9b:80:01:6b (227) b0:c6:9b:80:01:5c (255) b0:c6:9b:80:01:5c ( 0) b0:c6:9b:80:01:45 3.830s (223) b0:c6:9b:80:01:5f [ wlan0]: b0:c6:9b:80:01:5c (209) b0:c6:9b:80:01:6b ( 0) b0:c6:9b:80:01:6b ( 0) b0:c6:9b:80:01:5f (223) b0:c6:9b:80:01:6b 4.520s (255) b0:c6:9b:80:01:6b [ wlan0]: b0:c6:9b:80:01:5f (206) b0:c6:9b:80:01:5c (245) b0:c6:9b:80:01:6b (255) b0:c6:9b:80:01:6b (251) b0:c6:9b:80:01:3b 1.570s (237) b0:c6:9b:80:01:5f [ wlan0]: b0:c6:9b:80:01:5c (226) b0:c6:9b:80:01:6b ( 0) b0:c6:9b:80:01:6b ( 0) b0:c6:9b:80:01:5f (237) b0:c6:9b:80:01:5f 3.520s (255) b0:c6:9b:80:01:5f [ wlan0]: b0:c6:9b:80:01:6b (231) b0:c6:9b:80:01:6b (227) b0:c6:9b:80:01:5c (244) b0:c6:9b:80:01:5f (255)

Now I can nerver reach b0:c6:9b:80:01:43. Anyone tell me why this happens? And, what does "Drop packet: packet within seqno protection time" mean? What is the "seqno protection time"? Any help will be appreciated and thanks in advance.
