EcoNet was a vendor, they existed alongside of Airoha (both were 
subsidiaries of Mediatek). They ended up being bought out by Airoha in 
2021 and the name has been retired from usage. They did share a lot of 
technology between them, but Airoha focused on ARM devices while EcoNet 
only ever sold MIPS devices.

Airoha currently lists one of the old EcoNet MIPS SoCs on their website, 
and may have offered more in the past - but all of the Linux / OpenWrt 
support for "airoha,*" so far has been for ARM devices only. I've been 
promoting the idea that anything MIPS should be called EcoNet and 
anything ARM should be called Airoha.

Thanks,

Caleb
