Update the test status for Intel part. Till now dpdk22.07-rc3 test execution rate is 65%, find 2 new bugs, No.2 is critical bug. No.1, "Bug 1048 - [dpdk-22.07rc3] i40e_rss_input/flow_query: RSS types is not displayed tests failed". Only display failed, there is no fix yet. No.2, [dpdk-22.07rc3]The performance of X710 drop about 45% when testing nic_single_core: has fix and verify passed.
http://patchwork.dpdk.org/project/dpdk/patch/[email protected]/ ---Need push to merge.

Known critical bugs:
1, The performance of virtio PVP multi_paths has a drop(~about 5%) between DPDK22.07-rc2 and DPDK-22.03
split ring has fix, http://patchwork.dpdk.org/project/dpdk/patch/[email protected]/ ---Need verify then need push to merge. packed ring has no fix, Intel Dev is investigating.
2, Bug 1044 - [dpdk-22.07] ice_iavf_fdir: the ipv4/6 gtpu_eh rule not take effect
has fix, http://patches.dpdk.org/project/dpdk/patch/[email protected]/ ---Need push to merge.
