[PATCH net-next 0/2] net: econet: add EcoNet EN751221 ethernet driver

[Caleb James DeLisle]

The EcoNet EN751221 SoC has an Ethernet device with two ports and two
DMA engines (internally called "QDMA" because they handle both QoS and
DMA). It is fairly similar to the MediaTek and Airoha drivers, but
distinct enough that attempts to attach to those did not prove
fruitful. This ethernet device shows up in the chips based on the
EN751221 die, and also in the EN7528 chip with minor differences.

This ethernet device also has a "packet processing engine" similar to
that of the MediaTek eth driver, but that is not supported in this
driver.

This driver has been used as an OpenWrt package for about 6 months but
was not contributed until now because there was no DSA switch support
for these devices.
