I recall reading on the list that netmap maintains a TX ring and as such 
it is not friendly to Click configs that can hold on to some packets for 
a while.

FromDevice(ethX) -> cl::Classifier(...)[0]
                  -> Queue
                  -> DelayShaper(DELAY)
                  -> outQ;

cl[1] -> outQ;

Any clarifications from people familiar with netmap?

ixgb patches still require 2.6.24.7 kernel as there is no newer kernel 
that supports poll_on/poll_off in the netdevice.
