Hi,
Here is some printouts from EM7565 that might be of interest. The addition
in qcserial/qmi_wwan was enough, but I will do some more testing before I
settle for the changes (and post them here).
As default it shows only one ethernet interface, but there is a mismatch
between the USB configuration which is 50D and the interfaces available. I
will test to change these and see if has any effect. Still, it looks like
default, but not according to USBCOMP. I check further.

EM7565
OK
AT!USBCOMP?
Config Index: 1
Config Type: 3 (Generic)
Interface bitmask: 0000050D (diag,nmea,modem,rmnet0,rmnet1)
OK
AT!USBCOMP=?
!USBCOMP:
AT!USBCOMP=<Config Index>,<Config Type>,<Interface bitmask>
<Config Index> - configuration index to which the composition
applies, should be 1
<Config Type> - 1:MBIM USBIF, 2:PCIE USBIF, 3:Legacy-Generic,
4:RNDIS
<Interface bitmask> - DIAG - 0x00000001,
NMEA - 0x00000004,
MODEM - 0x00000008,
RMNET0 - 0x00000100,
RMNET1 - 0x00000400,
MBIM - 0x00001000,
e.g.
10D - diag, nmea, modem, rmnet interfaces enabled
1009 - diag, modem, mbim interfaces enabled
The default configuration is:
at!usbcomp=1,3,10F
OK
