The RM9200 supports one frame being sent while another one is waiting in queue. This avoids the dead time that follows the emission of a frame and which prevents one from reaching line speed. Right now the driver supports only a single skb, so we'll first replace the rm9200-specific skb info with an array of two macb_tx_skb (already used by other drivers). This patch only moves the skb_length to txq[0].size and skb_physaddr to skb[0].mapping but doesn't perform any other change. It already uses [desc] in order to minimize future changes.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
