Subject: [PATCH 01/12] net: hns3: code optimization for debugfs related to
 "dump reg"

For making the code more readable, this patch uses a array to
keep the information about the dumping register, and then uses
it to parse the parameter cmd_buf which passing into
hclge_dbg_dump_reg_cmd().

Also replaces parameter "base" of kstrtouint with 0 in the
hclge_dbg_dump_reg_common(), which makes it more flexible.

Subject: [PATCH 03/12] net: hns3: modify base parameter of kstrtouint in
 hclge_dbg_dump_tm_map

This patch replaces kstrtouint()'s patameter base with 0 in the
hclge_dbg_dump_tm_mac(), which makes it more flexible. Also
uses a macro to replace string "dump tm map", since it has been
used multiple times.

Subject: [PATCH 06/12] net: hns3: make some reusable codes into a function

In hclge_dcb.c, these pair of codes:
	hclge_notify_client(hdev, HNAE3_DOWN_CLIENT);
	hclge_notify_client(hdev, HNAE3_UNINIT_CLIENT);
and
	hclge_notify_client(hdev, HNAE3_INIT_CLIENT);
	hclge_notify_client(hdev, HNAE3_UP_CLIENT);
are called many times, so make them into a function.

 fails

Currently, the reset interrupt will be cleared firstly, so when
reset fails, if interrupt status register has reset interrupt,
it means there is a new coming reset.

Subject: [PATCH 12/12] net: hns3: not allow SSU loopback while execute ethtool
 -t dev

The current loopback mode is to add 0x1F to the SMAC address
as the DMAC address and enable the promiscuous mode.
However, if the VF address is the same as the DMAC address,
the loopback test fails.

Loopback can be enabled in three places: SSU, MAC, and serdes.
By default, SSU loopback is enabled, so if the SMAC and the DMAC
are the same, the packets are looped back in the SSU. If SSU loopback
is disabled, packets can reach MAC even if SMAC is the same as DMAC.

Therefore, this patch disables the SSU loopback before the loopback
test. In this way, the SMAC and DMAC can be the same, and the
promiscuous mode does not need to be enabled. And this is not
valid in version 0x20.

This patch also uses a macro to replace 0x1F.
