Jacob Keller bbd95160a0 ice: fix vf->num_mac count with port representors
The ice_vc_repr_add_mac() function indicates that it does not store the MAC
address filters in the firmware. However, it still increments vf->num_mac.
This is incorrect, as vf->num_mac should represent the number of MAC
filters currently programmed to firmware.

Indeed, we only perform this increment if the requested filter is a unicast
address that doesn't match the existing vf->hw_lan_addr. In addition,
ice_vc_repr_del_mac() does not decrement the vf->num_mac counter. This
results in the counter becoming out of sync with the actual count.

As it turns out, vf->num_mac is currently only used in legacy made without
port representors. The single place where the value is checked is for
enforcing a filter limit on untrusted VFs.

Upcoming patches to support VF Live Migration will use this value when
determining the size of the TLV for MAC address filters. Fix the
representor mode function to stop incrementing the counter incorrectly.

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 reStructuredText 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.
