Commitf949a12fd6("net: dsa: bcm_sf2: fix buffer overflow doing set_rxnfc") tried to fix the some user controlled buffer overflows in bcm_sf2_cfp_rule_set() and bcm_sf2_cfp_rule_del() but the fix was using CFP_NUM_RULES, which while it is correct not to overflow the bitmaps, is not representative of what the device actually supports. Correct that by using bcm_sf2_cfp_rule_size() instead. The latter subtracts the number of rules by 1, so change the checks from greater than or equal to greater than accordingly.

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.
