Could you share that piece of code so I don't have to duplicate
that effort?

vlan1
ifb1
vlan2
vlan3
ifb2
vlan4
dhcp daemon would bind to ifb1 and use pktinfo cmsg to figure
out whether the packet was received on vlan1 or vlan2, the
actual physical device is of no interest anymore.
Looking at your ifb code I see that you set skb->dev based on
iif and update iif unconditionally. I see a lot of problems
with this, firstly iif is already updated in the mirred action,
secondly iif doesn't necessarily point to the device the packet
was last seen on. Could you maybe explain the policy of iif
you have in mind, it doesn't seem very consistent.
BTW, why does ifb have a hard header length? The resulting
push and pull only slows things down.
