[support] MCoA doesn't read router advertisements

[Eriza Hafid Fazli]

Hi Romain,

actually what I was trying to say was that the MR doesn't seem to 
receive the RAs at all. I attached the log in this email.  There are 
several "__md_discover_router: discover link on iface eth1 (3)", but 
then it doesn't proceed with md_recv_ra, etc., although I can still see 
the RAs when I run tcpdump on eth1.

And this happens only when I restart mip6d; on the first run everything 
went OK.

Thanks,
Eriza
