After SRIOV has been enabled and disabled, the MSIX vectors assigned to the VFs have to be re-initialized. Otherwise they cannot be re-used by the PF. For example, increasing the number of PF rings after disabling SRIOV may fail if the PF uses MSIX vectors previously assigned to the VFs. To fix this, we add logic in bnxt_restore_pf_fw_resources() to close the NIC, clear and re-init MSIX, and re-open the 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.
