Mon Jun 8 04:21:28 CEST 2015
From: Marvin Liu <yong.liu at intel.com>
There're eight cases contained in this suite.
1) test_vxlan_ipv4_detect
Check whether FVL card can detect vxlan packets.
2) test_vxlan_ipv6_detect
Check whether FVL card can detect vxlan packets contain ipv6 header.
3) test_vxlan_ipv4_checksum_offload
Check hardware checksum work fine with vxlan packets.
4) test_vxlan_ipv6_checksum_offload
Check hardware checksum work fine with vxlan packets contain ipv6 header.
5) test_tunnel_filter
Check FVL tunnel filter can work with vxlan packets.
6) test_tunnel_filter_invalid
Check invalid tunnel filter command can normally handled.
7) test_perf_vxlan_tunnelfilter_performance_2ports
Performance test of vxlan tunnel filter on FVL.
8) test_perf_vxlan_checksum_performance_2ports
Performance test of vxlan hardware chksum offload.
