[dpdk-dev] [PATCH 04/26] net/octeontx/base: add base BGX operations

[Jerin Jacob <jerin.jacob@caviumnetworks.com>]

BGX is an HW MAC interface. This patch adds the basic BGX 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 physical port identifier.
