[RFC PATCH 12/14] KVM-test: Add a subtest of netperf

Amos Kong
2010-07-20T01:36:39Z

Add network load by netperf, server is launched on guest, execute netperf
client with different protocols on host. if all clients execute successfully,
case will be pass. Test result will be record into result.txt.
Now this case only tests with "TCP_RR TCP_CRR UDP_RR TCP_STREAM TCP_MAERTS
TCP_SENDFILE UDP_STREAM". DLPI only supported by Unix, unix domain test is
not necessary, so drop test of DLPI and unix domain.
