Subject: [PATCH v2 0/6] Add FDMA support on ocelot switch driver
Date: Wed,  3 Nov 2021 10:19:37 +0100	[thread overview]
Message-ID: <20211103091943.3878621-1-clement.leger@bootlin.com> (raw)

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.

------------------
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
