A mcam rule described by mcam_rule struct has all the info such as the hardware MCAM entry number, match criteria and corresponding action etc. All mcam rules are stored in a linked list mcam->rules. When adding/updating a rule to the mcam->rules it is checked if a rule already exists for the mcam entry. If the rule already exists, the same rule is updated instead of creating new rule. This way only one mcam_rule exists for the only one default unicast entry installed by AF. But a PF/VF can get different NIXLF (or default unicast entry number) after a attach-detach-attach sequence. When that happens mcam_rules list end up with two default unicast rules. Fix the problem by deleting the default unicast rule list node always when disabling mcam rules.

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.
