macb: Add device tree properties that allow configuration of the AXI max pipeline register net: macb: add support for ethtool interrupt moderation configuration Only global throttling of rx or tx by time quanta is supported. Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com> macb: add platform device shutdown function. Prevents AXI master over PCIE from hanging when the host is rebooted. net: macb: increase polling interval for MDIO completion MDIO is a slow bus (single-digit MHz). Polling at 1us intervals is a bit aggressive, so increase to 100us as the transaction usually takes 100-200us to complete.

Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com> net: macb: Support the phy-reset-gpios property Allow a PHY to be reset with an optional GPIO. The reset duration can be specified in milliseconds - the default is 10ms. Signed-off-by: Phil Elwell <phil@raspberrypi.com> drivers: net: macb: close device on driver shutdown Fix some suspicious locking and instead call into macb_close, which deregisters and frees all resources the corresponding macb_open claimed. Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com> net: macb: add hack to prevent TX stalls in a quiet system See https://github.com/raspberrypi/linux-2712/issues/89 There is some critical window during TX where a further write to the TSTART bit while TX is active does not cause newly queued TX descriptors to be consumed. For now "wait a bit, then try anyway" seems to work. Requires further investigation, but this unsticks NFS reliably. Signed-off-by: Jonathan Bell <jonathan@raspberrypi.com> net: macb: set default interrupt moderation for GEM hardware Defaulting to intmod = 0 is antisocial, as the MAC can generate over 130,000 interrupts per second. 50us is a sensible default.

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.
