Basing on xmit_more flag of the skb, TX descriptors can be concatenated before flushing. This commit delay Tx descriptor flush if the queue is running and if there is more skb's to send. A maximum allowed number of descriptors for flushing at once due to MVNETA_TXQ_UPDATE_REG(q) reqisters limitation, is 255. Because of that a new macro was added (MVNETA_TXQ_DEC_SENT_MASK) in order to ensure that concatenated amount of descriptor does not exceed that value.

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.
