SubjectRe: [PATCH 0/5] drivers/net: add NXP FEC-UIO driver
Date
[linux-devel@linux.nxdi.nxp.com doesn't exist in the public, which is quite
annoying when you reply to an email and the MTA doesn't accept it due to
invalid domains]

Could you elaborate for what this driver is needed? Doesn't the imx8mm
already have a network driver? What is the difference between them?

As a user, I couldn't find what this is all about, neither in this
commit message nor in the Kconfig help text.
