All,

Update the test status for Intel part. Till now dpdk22.07-rc4 regression is almost finished, two new bugs are found.
The high issue about "[dpdk-22.07]loopback_virtio_user_server_mode/server_mode_reconnect_with_split_all_path_payload_check: the first packet payload is different from the ohter packets in the same queue".
	It has fix link: http://patchwork.dpdk.org/project/dpdk/patch/20220712100447.104162-1-maxime.coquelin@redhat.com/, Intel validation team has completed validtion test for the patch, no new issue is found.
Other one issue about "vswitch_sample_cbdma:perf_pvp_vhost_async_operation_with_cbdma_2_channels: virtio-user will drop all the packets when sending large 1280 Byte packets".
	It has fix link: https://patches.dpdk.org/project/dpdk/patch/20220714051106.1134222-1-wenwux.ma@intel.com/ and tested-by by Intel, but no acked-by yet.
