I realized when we were adding unicast addresses we were enabling
promiscuous mode. I did a bit of digging and realized we had overlooked
setting the driver private flag to indicate we supported unicast filtering.
Example below shows the table with 00deadbeef01 as the main NIC address,
and 5 additional addresses in the 00deadbeefX0 format.
# cat $dbgfs/mac_addr
Idx S TCAM Bitmap Addr/Mask

000000000000
26 1 00100000,00000000 00deadbeef40
000000000000
27 1 00100000,00000000 00deadbeef30
000000000000
28 1 00100000,00000000 00deadbeef20
000000000000
29 1 00100000,00000000 00deadbeef10
000000000000
30 1 00100000,00000000 00deadbeef01
000000000000
31 0 00000000,00000000 000000000000
000000000000
Before rule 31 would be active. With this change it correctly sticks
to just the unicast filters.

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.
