# Important Notes:
#
# Two local dependencies should be ready before build container image with the Dockerfile.
# - MLNX_OFED: Please download it from the official website
#   `https://network.nvidia.com/products/infiniband-drivers/linux/mlnx_ofed/`
#   to the local fileserver indicated by the ARG `MLNX_OFED`.
#   We cannot download it in the Dockerfile automatically for the authentication
#   restriction of the website.
# - RPM_PKGCONFIG: The `pkg-config` tool of v0.29.2 is required to build DPVS.
#   However, the default installation version on centos7 is v0.27.1. You need to
#   download it or build the v0.29.2 RPM from source and put it to the the local
#   fileserver indicated by the ARG `RPM_PKGCONFIG`. Alternatively, building a
#   binary `pkg-config` and installing it in the local binary path is also ok.
#
#   No kernel dependencies of dpdk/dpvs or network driver are built and installed.
#   You should ensure the host has installed the drivers before running a dpvs
#   container on it.
#
