Subject: [PATCH net-next 0/5] net: lan966x: Add support for FDMA
Date: Thu, 17 Mar 2022 19:51:54 +0100	[thread overview]
Message-ID: <20220317185159.1661469-1-horatiu.vultur@microchip.com> (raw)

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.
