When multiple liquidio NICs are plugged in, the first insmod of the PF driver succeeds. But after an rmmod, a subsequent insmod fails. Reason is during rmmod, the PF driver resets the Octeon of only one of the NICs; it neglects to reset the Octeons of the other NICs. Fix the insmod failure by adding the missing Octeon resets at rmmod. Keep a per-NIC refcount that indicates the number of active PFs in a given NIC. When the refcount goes to zero, then reset the Octeon of that NIC.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
