More info on this:
Looking at the code, the the ICMP6 control socket error is occurring
because sock_register isn't called for inet6 until after the ICMP6 control
socket is created (in af_inet6.c).
However, the ICMP6 control socket create calls sock_create, which requires
sock_register to have already been called.
I have made the below change, which moves the protocol family registration
higher up in the code. It seems to make ipv6 work now.
However, I'm concerned that this gives a small amount of time when the
family is registered but not fully initialised.
Is this bad?
