LAN Test Improvements

Run the LAN certification tests early during driver development

New Feature Test Suites Quality of Service (QoS) Single Root IO Virtualization (SR-IOV) RDMA Receive Segment Coalescing (RSC)

Other New Tests to Watch For Standardized keywords Generic NDIS miniport tests Offload parity Power requirements New Wake-On-LAN tests

NDIS Filter Testing

Filter Testing Techniques Utilize the NDISTest LAN tests Filters for the Hyper-V Extensible Switch Focus on plug-and-play Utilize the device fundamentals tests
