I think what I'm most confused about this pkt_sched.h thing is that the code
works with version 2.4.7 of iproute2 ... in 2.4.7 of iproute2 there is no
pkt_sched.h anywhere to be found in the source code.
However in the newest version of iproute2 which I am trying to get this
functionality to work in, there is a pkt_sched.h
My last observation, is that in q_xcp.h it includes pkt_sched_xcp.h which has:
struct tc_xcp_qopt
{
__u32 first_param;
__u32 second_param;
};
So I am assuming i need to add something like the enum thing to pkt_sched.h in
the new iproute2 source... however what are the proper names I need to use in
the enum? I don't expect you to know the names, however, what do i match them
with?
Thanks!
George
