Now that we have established the queue mapping between the switch port egress queues and the SYSTEMPORT egress queues, we can turn on Advanced Congestion Buffering (ACB) at the SYSTEMPORT level. This enables the Ethernet MAC controller to get out of band flow control information directly from the switch port and queue that it monitors such that its internal TDMA can be appropriately backpressured.

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.
