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> |
