Cell-index value is obtained from Device Tree and then used to calculate the index for accessing arrays port_mfl[], mac_mfl[] and intr_mng[]. In case of broken DT due to any error cell-index can contain any value and it is possible to go beyond the array boundaries which can lead at least to memory corruption. Validate cell-index value obtained from Device Tree. Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
