selftests/bpf: xdp_hw_metadata reduce sleep interval
In current ping-pong design, xdp_hw_metadata will wait until the packet transmission completely done, then only start to receive the next packet. The current sleep interval is 10ms, which is unnecessary large. Typically, a NIC does not need such a long time to transmit a packet. Furthermore, during this 10ms sleep time, the app is unable to receive incoming packets. Therefore, this commit reduce sleep interval to 10us, so that xdp_hw_metadata is able to support periodic packets with shorter interval. 10us * 500 = 5ms should be enough for packet transmission and status retrieval.
