Subject: [PATCH 0/3] Add FDMA support on ocelot switch driver

This series adds support for the Frame DMA present on the VSC7514
switch. The FDMA is able to extract and inject packets on the various
ethernet interfaces present on the switch.

While adding FDMA support, bindings were switched from .txt to .yaml
and mac address read from device-tree was added to allow be set instead
of using random mac address.

Clément Léger (3):
  net: ocelot: add support to get mac from device-tree
  dt-bindings: net: convert mscc,vsc7514-switch bindings to yaml
  net: ocelot: add FDMA support
