RZ/A1H (R7S72100) Ether controller doesn't seem to have the TX counter registers like TROCR/CDCR/LCCR (or at least they are still undocumented like some TSU registers), so we bail out of sh_eth_get_stats() early in this case. Currently we are calling sh_eth_is_rz_fast_ether() in order to check for this, but it would be simpler to check the new 'no_tx_cntrs' bitfield in the 'struct sh_eth_cpu_data'; then we'd be able to remove sh_eth_is_rz_fast_ether() as there would be no callers left...

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.
