[mpls-linux-general] tcp problem

[<mi...@en...>]

Hi,
I think that by adding the line "rt->u.dst.pmtu -= 4;" to

linux/net/ipv4/route.c , rt_set_nexthop() ,

at

switch(moi->moi_instruction[i].mi_opcode),

in

case MPLS_OP_FWD:

       rt->u.dst.pmtu -= 4; /* <---- add this *** */
       moi = (struct mpls_out_info*) moi->moi_instruction[i].mi_data;
       goto mpls_again;
       break;

one can correct the small problem that lead to tha jaming of tcp links
established over mpls for linux when high traffic occured over that link.
I've tried it, and it works fine.
