Hi

I have seen Mr.Ping Pan's implementation of this. This seems to be just
for receiving a packet with some IP option through a raw IP socket. This
doesn't seem to be containing the kernel processing part of a packet
with router alert option. In netinet6 I have seen that the ip6_input()
function sets
	ours = 1;
when it gets a packet with router alert option. Is something similar done
in case of IPv4 too? If that's the case, I couldn't figure it out in this
patch. Or is it already there in the standard kernel itself? Could some
one tell me how a packet with router alert option is handled in
ip_input(), or give me some pointers to some description of this
processing?

thanks & regards
Madhavi.
