There are limited number CPT LFs (example 64 LFs on cn10k) and these LFs are allocated/attached to CPT VF on its creation. cptpf sysfs parameter "kvf_limits" defines number of CPT LFs per CPT VF. Default "kvf_limits" is initialized to zero and if kvf_limits is zero then number of LF allocated are equal to online cpus in system. For example on 24 core system, 24 CPT LFs will be attached per VF. That means no CPT LF available when creating more than 2 CPT VFs on system which have total 64 LFs. Although VFs gets created but no LF attached to it. There seems no reason to default allocate as many LFs as many online cpus in system. This patch initializes "kvf_limits" to one to limit one LF allocated per CPT VF. "kvf_limits" can be changed in range of 1 to number-of-online-cpus via sysfs.

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.
