[dpdk-dev] [PATCH v4 2/8] net/dpaa: add VSP support in FMLIB

[Hemant Agrawal <hemant.agrawal@nxp.com>]

From: Jun Yang <jun.yang@nxp.com>

This patch adds support for VSP (Virtual Storage Profile)
in fmlib routines.
VSP allow a network interface to be divided into physical
and virtual instance(s).
The concept is very similar to SRIOV.
