In preparation for supporting multiple CPU ports, remove dst->master_netdev and ds->master_netdev and replace them with only one instance of the common object we have for a port: struct dsa_port::netdev. ds->master_netdev is currently write only and would be helpful in the case where we have two switches, both with CPU ports, and also connected within each other, which the multi-CPU port patch series would address. While at it, introduce a helper function used in net/dsa/slave.c to immediately get a reference on the master network device called dsa_master_netdev().

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.
