As far as I'm aware, none of the HW platforms that have the mvneta IP
as Ethernet MAC have an IOMMU/SMMU or similar. The more recent Marvell
platforms are using the mvpp2 IP instead.

Clearly, I am no longer actively working on Marvell platforms, and it
would certainly be fine to see other people step up to maintain the
mvneta driver and drop my entry.

Best regards,

Thomas
