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

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.
