Hi

Update the test status for Intel part. Till now dpdk22.07-rc4 regression is running smooth.
But we find one 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",
Bad commit id is cd79d1b030bd69df31fd401d1b48c23df0f71d00(which is used to fix the performance drop of split ring)

    vhost: fix unnecessary dirty page logging

    The dirty page logging is only required in vhost enqueue direction for
    live migration. This patch removes the unnecessary dirty page logging
    in vhost dequeue direction. Otherwise, it will result in a performance
    drop. Some if-else judgements are also optimized to improve performance.

    Fixes: 6d823bb302c7 ("vhost: prepare sync for descriptor to mbuf refactoring")
    Fixes: b6eee3e83402 ("vhost: fix sync dequeue offload")
