Hi, I created a socket with AF_INET6, SOCK_RAW, IPPROTO_RAW arguments. Framed a packet including the IPv6 header destined to a global IPv6 unicast address for which a route exists in the stack and sent it through an interface (specified with IPV6_PKTINFO). The packet came out the device properly. Now when I tried to make the network device down, i get the following messages continuously on the console. "unregister_netdevice: waiting for eth1 to become free. Usage count = 3" Seems like the device refcnt leaked when passing packet through rawv6_sendmsg(). I am using linux version 2.6.14 Appreciate your help on this problem.
