Many routers have long router advertisment interval configured by default. The Neighbor Discovery protocol (RFC4861) has defined default MaxRtrAdvInterval value as 600 seconds and MinRtrAdvInterval as 0.33*MaxRtrAdvInterval. This makes net_ipv6_autoconf fails more often than not as currently it passively listens the RA message to perfom address autoconfiguration. This patch tries to send router solicitation to overcome the problem of long RA interval. v2: use cpu_to_be macro for network byte order conversion add missing error handling
