Heres what it would look at ingress:
step 0: coming from wire via eth0,
dev=eth0, input_dev=eth0
step 1: redirect to ifb0, leaving redirect
dev=ifb0, input_dev=eth0
step 2: leaving ifb0, coming back to ingress side of stack
dev= eth0, input_dev=ifb0
That creates a nice loop on ingress. Upon reentering the
stack with skb->dev set to eth0 again we'll go through the
same ingress filters as the first time and we'll hit ifb0
again over and over. Are you suggesting everyone has to
insert a pass action matching input_dev in order to escape
the loop when using ifb?
Bit 8 of skb->tc_verd is set by IFB, so packet isn't reclassify.
This bit avoid the loop.
