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.

# Basic Intel(R) NIC testing
* Build or compile:  
 *Build: cover the build test combination with latest GCC/Clang version and the popular OS revision such as Ubuntu20.04, Ubuntu22.04, Fedora36, RHEL8.6 etc.
  - All test passed.

* PF/VF(i40e, ixgbe): test scenarios including PF/VF-RTE_FLOW/TSO/Jumboframe/checksum offload/VLAN/VXLAN, etc. 
	- All test done. No new issue is found
    
* PF/VF(ice): test scenarios including Switch features/Package Management/Flow Director/Advanced Tx/Advanced RSS/ACL/DCF/Flexible Descriptor, etc.
	- All test done. No new issue is found. 
	
* Intel NIC single core/NIC performance: test scenarios including PF/VF single core performance test, RFC2544 Zero packet loss performance test, etc.
	- All test done. No new issue is found.
		
# Basic cryptodev and virtio testing
* Virtio: both function and performance test are covered. Such as PVP/Virtio_loopback/virtio-user loopback/virtio-net VM2VM perf testing/VMAWARE ESXI 7.0u3, etc.
	- All test done. Find two new bugs as above.

* Cryptodev: 
 *Function test: test scenarios including Cryptodev API testing/CompressDev ISA-L/QAT/ZLIB PMD Testing/FIPS, etc.
