I ran strace on olsr with ipv6 on OpenWrt r44764 on an alix2 with kernel
version 3.18.8, as well as on kernel version 3.14.34.  It appear that
with both kernels, olsrd opens two sockets on each interface.  However,
with kernel 3.14 only one of the sockets call recvfrom to get incoming
data, while on kernel 3.18 both of the sockets do.

Apparently, since the same UDP datagram is received on both sockets, it
sees the same seqno twice, hence the syslog message.
