DLB supports 4 class of service domains, to aid in managing the device bandwidth across ldb ports. This commit allows specifying which ldb ports will participate in the COS scheme, which class they are a part of, and the specific bandwidth percentage associated with each class. The cumulative bandwidth associated with the 4 classes must not exceed 100%. This feature is enabled on the command line, and will be documented in the DLB2 programmers guide.
