Jian Shen ccb18f0553 net: hns3: fix bug when PF set the duplicate MAC address for VFs
If the MAC address A is configured to vport A and then vport B. The MAC
address of vport A in the hardware becomes invalid. If the address of
vport A is changed to MAC address B, the driver needs to delete the MAC
address A of vport A. Due to the MAC address A of vport A has become
invalid in the hardware entry, so "-ENOENT" is returned. In this case, the
"used_umv_size" value recorded in driver is not updated. As a result, the
MAC entry status of the software is inconsistent with that of the hardware.

Therefore, the driver updates the umv size even if the MAC entry cannot be
found. Ensure that the software and hardware status is consistent.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
