[PATCH v5 0/7] support dump reigser names and filter them

[Jie Hai <haijie1@huawei.com>]

The registers can be dumped through the API rte_eth_dev_get_reg_info.
However, only register values are exported, which is inconvenient
for users to interpret. Therefore, an extension of the structure
"rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext
is added to support the capability of exporting the name of the
corresponding register and filtering by names.

The hns3 driver and telemetry are examples for that.
