To support setting the pause parameters, the driver can no longer just mirror the PHY. The set_pauseparam feature allows the driver to force the setting in the MAC, regardless of how the PHY is configured. This means that we now need to maintain an internal state for pause frame support, and so get_pauseparam also needs to be updated. If the interface is already running when the setting is changed, then the interface is reset. Note that if the MAC is configured to enable RX pause frame support (i.e. it transmits pause frames to throttle the other end), but the PHY is configured to block those frames, then the feature will not work. Also some buffer size initialization code into emac_init_adapter(), so that it lives with similar code, including the initializtion of pause frame support.

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.
