 Log Message:
 PR kern/56348
 MTU discovery fails with IPv6 sockets bound to IPv4 mapped address
 
 pick up the IPv4 route for IPv4 mapped IPv6 address to get the correct
 MTU and not any unrelated/inappropriate MTU from IPv6 routes. IPv4 mapped
 IPv6 addresses are always handled by the IPv4 stack and MTU discovery
 is solely handled with the IPv4 routing table.
