How to raise USB 4G modem on NetBSD?

Question

USB

Raspberry Pi has NetBSD installed.
I inserted a Yota USB modem.
She defined it like this:

# /usr/sbin/usbdevs
addr 1: DWC2 root hub, NetBSD
 addr 2: product 9512, vendor 0424
  addr 3: product ec00, vendor 0424
  addr 4: Modem Yota, GCT SEMICONDUCTOR Inc

But /sbin/ifconfig does not show the new network interface (unlike when Linux is loaded)
How do I bring up the interface?

Answer 1

You need to configure ppp. To my mind
