[ upstream commit 19e67d8ebced5cb12829f75c70e6c497b5925e82 ]

This problem occurs in the following scenarios:
1) reset is encountered when the adapter is running.
2) set a new default MAC address

After the above two steps, the old default MAC address should be not
take effect. But the current behavior is contrary to that. This is due
to the change of the "default_addr_setted" in hw->mac from 'true' to
'false' after the reset. As a result, the old MAC address is not removed
when the new default MAC address is set. This variable controls whether
to delete the old default MAC address when setting the default MAC
address. It is only used when the mac_addr_set API is called for the
first time. In fact, when a unicast MAC address is deleted, if the
address isn't in the MAC address table, the driver doesn't return
failure. So this patch remove the redundant and troublesome variables to
resolve this problem.

Fixes: 7d7f9f80bbfb ("net/hns3: support MAC address related operations")

Hi Huisong,

Thanks for backporting.

Subject "20.11" is missing, append to avoid it mixed with other LTS.
