     28 #   Verify that the kernel is not crashed with a connection to with
     29 #   the following condition:
     30 #     - The version of IP is IPv4
     31 #     - Network is not delayed
     32 #     - IPsec is not used
     33 #     - Disable window scaling
     34 #     - Disable Nagle algorithm
     35 #     - Enable TCP Duplicate SACK support
     36 #     - Enable SACK Support
     37 #     - No packet are lost
     38 #     - Disable TSO if it is avalable
