Currently, the global variables rxq_number and txq_number hold the number of per-port TXQs and RXQs. Until now, such numbers were constant regardless of the driver configuration. As we are going to introduce different modes for TX and RX queues, these numbers will depend on the configuration (PPv2.1 vs. PPv2.2, exact queue distribution logic). Therefore, as a preparation, we move the number of RXQs and TXQs in the 'struct mvpp2_port' structure, next to the RXQs and TXQs descriptor arrays. For now, they remain initialized to the same default values as rxq_number/txq_number used to be initialized, but this will change in future commits. The only non-mechanical change in this patch is that the check to verify hardware constraints on the number of RXQs and TXQs is moved from mvpp2_probe() to mvpp2_port_probe(), since it's now in mvpp2_port_probe() that we initialize the per-port count of RXQ and TXQ.

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.
