12f46bc1d4 net: hns3: Refine hns3_get_link_ksettings()
In the previous implement, the query operation for fibre port and copper
port are mixed. This patch refines it by seperating them based on the port
type.

7a0a928402 net: hns3: Remove redundant codes of query advertised flow control abilitiy
If the advertised flow control ability has been fetched using
phy_ethtool_ksettings_get() or hclge_get_link_mode() then it is
unnecessary to fetch them again later using hclge_get_flowctrl_adv().
This patch removes it.

7f7d9e501f net: hns3: Change the dst mac addr of loopback packet
Currently, the dst mac addr of loopback packet is the same as
the host' mac addr, the SSU component may loop back the packet
to host before the packet reaches mac or serdes, which will defect
the purpose of mac or serdes selftest.

This patch changes it by adding 0x1f to the last byte of dst mac
addr.

3f8601f0f5 net: hns3: Fix ping exited problem when doing lp selftest
When ping is runnig and user executes the loopback selftest, the
ping cmd will stop and exit.

This patch fixes it by using the hns3_nic_net_open/stop to offline
the netdev when doing loopback selftest.

0f29fc23b2 net: hns3: Fix for loopback selftest failed problem
Tqp and mac need to be enabled when doing loopback selftest,
ae_algo->ops->start/stop is used to do the job, there is a
time window between ae_algo->ops->start/stop and loopback setup,
which will cause selftest failed problem when there is frame
coming in during that time window.

This patch fixes it by enabling the tqp and mac during loopback
setup process.

7b763f3f7e net: hns3: Clear TX/RX rings when stopping port & un-initializing client
When we down the port, some packets are left in TX/RX buffer. When we
up the port again, these old packets are forwarded to protocol stack
or are sent to internet. It will make some problem. TX/RX buffer should
be cleared when stopping port. This patch adds some function to ensure
the buffer is clean when port is started. We should clear the rings
when clients are being un-initialized as well.
