-gact <ACTION> [RAND] [INDEX]
-
-Where: 
-       ACTION := reclassify | drop | continue | pass | ok 
-       RAND := random <RANDTYPE> <ACTION> <VAL>
-       RANDTYPE := netrand | determ
-        VAL : = value not exceeding 10000
-        INDEX := index value used
-      
-ACTION semantics
-- pass and ok are equivalent to accept
-- continue allows to restart classification lookup
-- drop drops packets
-- reclassify implies continue classification where we left off

-randomization
---------------
-
-At the moment there are only two algorithms. One is deterministic
-and the other uses internal kernel netrand.
-
-Examples:
-
-Rules can be installed on both ingress and egress - this shows ingress
-only

-tc qdisc add dev eth0 ingress

-tc filter add dev eth0 parent ffff: protocol ip prio 6 u32 match ip src \
