A local test found that repeated port start and stop operations during
the continuous SSE vector bufflist receiving process will cause the mbuf
resource to run out. The final positioning is when the port is stopped,
the mbuf of the pkt_first_seg pointer is not released. Resource

The following is Huawei hns3 PMD and DMA engine roadmap for DPDK 21.11
release:
* Support Tx prepare for bonding
* Support multi-process for testpmd
* Support DMA device framework
* Support DMA engine for Kunpeng 920
* Support refactor for hns3 PMD
* Support performance optimization for hns3 PMD
Hello Luca,
The testing with dpdk 20.11.3-rc1 from Red Hat looks good. We tested below
16 scenarios and all got PASS on RHEL8:

Function reentrancy test limits maximum number of iterations
simultaneously, however it doesn't free the 'fr_test_once'
memzones after the fact, so introduce freeing 'fr_test_once'
in ring/mempool/hash/fbk/lpm_clean.
Meanwhile, add the missing free for test case on main thread.
