KFDTest: simply P2PBandwidthTest case for specified source/destination
Only run the P2P test over the specified source and destination nodes if user already specify them Change-Id: Ia3c0195cead7f46e3e28507f3255d8c59a287ab8 Signed-off-by: shaoyunl <shaoyun.liu@amd.com> |

kfdtest: add P2POverheadTest
This is to measure the laterncy + overhead of sdma packet consumption on p2p. It is Similar with QueueLatency test. What's more, the queue's overhead with different workload show more details. test result on two gfx900.
