• all 4 ports are working in terms of ping(8) and nc(1)
• interrupt dispatching isn't prepared to run NetPerf yet.

• because we mitigate RX/TX descriptors in NetFPGA, some good managment is needed. Not sure why Linux driver code uses atomic operations in the interrupt handler. This is to be solved at the Brno meeting with John and Adam.
• polling(4) support
• definition for suspend/resume semantics is missing
• VLAN/Jumbo functionality isn't tested

This test was done with NetPerf default socket settings for both -t TCP_STREAM (TCP stream test) and -t UDP_STREAM (UDP stream test). Every test has been run 31 times. Result of each of tests is present on the X axis. Y axis represents result of the particular test.
