net/netvsc: add Hyper-V network device The driver supports Hyper-V networking directly like virtio for KVM or vmxnet3 for VMware. This code is based off of the FreeBSD driver. The file and variable names are kept the same to help with understanding (with most of the BSD style warts removed). This version supports the latest NetVSP 6.1 version and older versions.

net/netvsc: implement link state change callback Implement callback functionality on link state changes. This is not really driven off of interrupt file descriptor like most other PMD's. Instead, it happens when a link state change message arrives in the common ring buffer. Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com>

net/netvsc: support integrated VF Integrate accelerated networking support into netvsc PMD. This allows netvsc to manage VF without using failsafe or vdev_netvsc. For the exception vswitch path some tests like transmit get a 22% increase in packets/sec. For the VF path, the code is slightly shorter but has no real change in performance. Pro: * using netvsc is more like other DPDK NIC's * the exception packet uses less CPU * much smaller code size * no locking required on VF transmit/receive path * no legacy Linux network device to get mangled by userspace * much simpler (1K vs 9K) LOC * unified extended statistics Con: * using netvsc has more complex startup model * no bifurcated driver support * no flow support (since host does not have flow API). * no tunnel offload support * no receive interrupt support Signed-off-by: Stephen Hemminger <sthemmin@microsoft.com>
