Writing into NPC MCAM1 and MCAM0 registers are suppressed if they happened to form a reserved combination. Hence clear and disable MCAM entries before update. For HRM: [CAM(1)]<n>=1, [CAM(0)]<n>=1: Reserved. The reserved combination is not allowed. Hardware suppresses any write to CAM(0) or CAM(1) that would result in the reserved combination for any CAM bit.

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.
