vlib: support Hyper-v/Azure VMBus
This patch adds support for VMBus to the VPP infrastructure. Since the only device that matters is the netvsc Poll Mode Driver in DPDK, the infrastructure is much simpler than PCI. Change-Id: Ie96c897ad9c426716c2398e4528688ce2217419b Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
