This feature adds support for source interface based load-balancing with Dynamic Load-Balancing ( DLB ) and Hash based Load-Balancing on Equal Cost Multi Path ( ECMP ) groups

This feature adds support for “Dynamic Load Balancing (DLB)” on Equal Cost Multi Path (ECMP) groups.
It is intended to help overcome the potential shortcomings of traditional hash-based load balancing by considering the traffic load of members of ECMP groups. DLB considers the state of the port while assigning egress ports to packets, resulting in a more even flow. The state of each port member is determined by measuring the amount of data transmitted from a given port and total number of packets enqueued to a given port.
