Description Dmitry Fleytman 2012-11-20 12:55:40 UTC 
Description of problem:

As we recently saw on NETKVM decreasing number of if's in driver's code increases performance significantly for data transfers with small packets.
Probably the same results are applicable for other drivers.
Re-factoring should be done for drivers' data-path.
