Hi All

If I redirect to an interface with

/sbin/tc qdisc add dev eth0 ingress
/sbin/tc filter add dev eth0 parent ffff:  protocol all prio 1 \
          u32  match u32  0 0 flowid 1:2 \
          action mirred egress redirect dev ifb0

Given that setup I can say:
1) all packets incoming thru eth0 will be *MOVED* to ifb0 output and do not
return to eth0.

I don't know what return to eth0 would mean for ingress - but I expect (untested), if you had some netfilter rule that said -i eth0 that it would still work for a packet that went through the ifb.

2) flowid X:Y is of no importance. I can write anything for X:Y.

I think that these get reinstated when the packet leaves ifb, which could I suppose affect things if it goes through another qdisc (I guess this would apply to egress more than ingress, eg. pfifo fast being default).

Are these assertives correct??

I don't know for sure, you need to test.
