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 reading from device-tree was added for testing purposes. Jumbo frame support was also added since it gives a large performance improvement with FDMA.
The series should be prefixed with net-next
------------------ Changes in V2: - Read MAC for each port and not as switch base MAC address - Add missing static for some functions in ocelot_fdma.c - Split change_mtu from fdma commit - Add jumbo support for register based xmit - Move precomputed header into ocelot_port struct - Remove use of QUIRK_ENDIAN_LITTLE due to misconfiguration for tests - Remove fragmented packet sending which has not been tested Clément Léger (6): net: ocelot: add support to get port mac from device-tree dt-bindings: net: convert mscc,vsc7514-switch bindings to yaml net: ocelot: pre-compute injection frame header content net: ocelot: add support for ndo_change_mtu net: ocelot: add FDMA support net: ocelot: add jumbo frame support for FDMA .../bindings/net/mscc,vsc7514-switch.yaml | 184 +++++ .../devicetree/bindings/net/mscc-ocelot.txt | 83 -- drivers/net/ethernet/mscc/Makefile | 1 + drivers/net/ethernet/mscc/ocelot.c | 23 +- drivers/net/ethernet/mscc/ocelot.h | 3 + drivers/net/ethernet/mscc/ocelot_fdma.c | 754 ++++++++++++++++++ drivers/net/ethernet/mscc/ocelot_fdma.h | 60 ++ drivers/net/ethernet/mscc/ocelot_net.c | 37 +- drivers/net/ethernet/mscc/ocelot_vsc7514.c | 15 + include/soc/mscc/ocelot.h | 7 + 10 files changed, 1075 insertions(+), 92 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/mscc,vsc7514-switch.yaml delete mode 100644 Documentation/devicetree/bindings/net/mscc-ocelot.txt create mode 100644 drivers/net/ethernet/mscc/ocelot_fdma.c create mode 100644 drivers/net/ethernet/mscc/ocelot_fdma.h
