hi all,

while going thru the ipv6 source code, i found that the frag_id was not in
the network byte order. I guess even in the case of IPv4, the id is not in
NBO. Is that intentional??? i checked freebsd and it gives the frag id in
NBO.
Anycase, i have attached the patch (against ip6_output.c/kernel 2.4.3) below
(notice that some people will do anything to get their name in the kernel
sources:)

regards,
imran
