Is the name predictable? I thought "eth%d" was considered
NET_NAME_ENUM?

For Ethernet-type devices, the interface name will follow the standard
convention: eth%d,
For normal IP interfaces, the interface will be created as mhi_swip%d/
mhi_hwip%d.
The naming will depend on the details provided through struct mhi_device_info.
Take a look again at my question. Why is NET_NAME_PREDICTABLE correct?
Justify it. Especially given what alloc_etherdev_mqs() does.
Andrew
You’re right—eth%d should use NET_NAME_ENUM. I’ll update the patch to use NET_NAME_ENUM for both Ethernet-type interfaces and for non-Ethernet (SW/HW IP) interfaces.
Thanks for the pointer.
