The q_vector names are based on the interface name with a driver prefix, the type of q_vector setup, and the queue number. We previously set the size of this variable to IFNAMSIZ + 9, which is incorrect, because we actually include a minimum of 14 characters extra beyond the interface name size. New versions of GCC since 7 include a new warning that detects this possible truncation and complains. We can fix this by increasing the size in case our interface name is too large to avoid truncation. We don't need to go beyond 14 because the compiler is smart enough to realize our values can never exceed size of 1. We do go up to 15 here because possible future changes may increase the number of queues beyond one digit. While we are here, also change some variables to be unsigned (since they are never negative) and stop using an extra unnecessary %s format specifier.

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.
