Staging: batman-adv: Fixing wrap-around bug in vis

Browse source

commit ea4ceb18b5 upstream.

When the seqno for a vis packet had a wrap around from i.e. 255 to 0,
add_packet() would falsely claim the older packet with the seqno 255 as
newer as the one with the seqno of 0 and would therefore ignore the new
packet. This happens with all following vis packets until the old vis
packet expires after 180 seconds timeout. This patch fixes this issue
and gets rid of these highly undesired 3min. breaks for the vis-server.
