cad78ca238
PKO is the packet output processing unit, which receives the packet from the core and sends to the BGX interface. This patch adds the basic PKO operation like open, close, start and stop. These operations are implemented through mailbox messages and kernel PF driver being the server to process the message with the logical port identifier.
