+================================
+TC Actions - Environmental Rules
+================================
+
+
+The "environmental" rules for authors of any new tc actions are:
+
+1) If you stealeth or borroweth any packet thou shalt be branching
+ from the righteous path and thou shalt cloneth.
+
+ For example if your action queues a packet to be processed later,
+ or intentionally branches by redirecting a packet, then you need to
+ clone the packet.
+
+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.
+
+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.
+
+The "environmental" rules for callers of actions (qdiscs etc) are:
+
+#) Thou art responsible for freeing anything returned as being
+ TC_ACT_SHOT/STOLEN/QUEUED. If none of TC_ACT_SHOT/STOLEN/QUEUED is
+ returned, then all is great and you don't need to do anything.
+
+Post on netdev if something is unclear.
