Currently when injecting or extracting a frame from CPU, the frame is given to the HW each word at a time. There is another way to inject/extract frames from CPU using FDMA(Frame Direct Memory Access). In this way the entire frame is given to the HW. This improves both RX and TX bitrate.
Horatiu Vultur (5): dt-bindings: net: lan966x: Extend with FDMA interrupt net: lan966x: Add registers that are used for FDMA. net: lan966x: Expose functions that are needed by FDMA net: lan966x: Add FDMA functionality net: lan96x: Update FDMA to change MTU.
