Huisong Li 7d8194517a sig-dpdk: sync some patches for PMD/LIB/APP
Sync some patches for hns3 PMD, telemetry and testpmd. And main
modifications are as follows:
 - backport some bugfixes for hns3
 - revert Tx performance optimization for hns3
 - add Rx/Tx descriptor dump feature for hns3
 - refactor some RSS commands for testpmd
 - add ethdev telemetry private dump
 - add dmadev telemetry
 - sync telemetry lib

Subject: [PATCH 126/189] net/hns3: support backplane media type
The 802.11 physical PMA sub-layer defines three media: copper, fiber and
backplane. For PMD, the backplane is similar to the fiber, the main
differences are that backplane doesn't have optical module.
Because the interface of firmware fiber is also applicable to the
backplane, this patch supports the backplane only through simple
extension.
