 or intentionally branches by redirecting a packet, then you need to
 clone the packet.
 
-There are certain fields in the skb tc_verd that need to be reset so we
-avoid loops, etc.  A few are generic enough that skb_act_clone()
-resets them for you, so invoke skb_act_clone() rather than skb_clone().

 2) If you munge any packet thou shalt call pskb_expand_head in the case
 someone else is referencing the skb. After that you "own" the skb.
-You must also tell us if it is ok to munge the packet (TC_OK2MUNGE),
-this way any action downstream can stomp on the packet.
 
 3) Dropping packets you don't own is a no-no. You simply return
 TC_ACT_SHOT to the caller and they will drop it.
