[dpdk-dev] [PATCH v2 07/26] net/octeontx/base: add base PKI operations

[Santosh Shukla <santosh.shukla@caviumnetworks.com>]

From: Jerin Jacob <jerin.jacob@caviumnetworks.com>

PKI is packet input unit, which receives the packet from the
BGX interface. This patch adds the basic PKI 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.
