Avoid setting adapter->num_vfs early in the init code path when using the max_vfs module parameter by passing it to ixgbe_enable_sriov() as a function parameter. This fixes an issue where if we failed to allocate vfinfo in __ixgbe_enable_sriov() the driver will crash with NULL pointer in ixgbe_disable_sriov() when attempting to free the vfinfo struct based on adapter->num_vfs. Also it cleans up the assignment of adapter->num_vfs since now it will only be set in __ixgbe_enable_sriov() and cleared in ixgbe_disable_sriov().

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.
