5G support in MBIM

[Hagstrom, Walter]

Hello,

I have an EM9190 Sierra Wireless 5G modem, this modem only supports MBIM and not QMI; when I make a 5G connection (I can see via !gstatus the modem is connected on 5G), MBIM does not advertise any 5G capabilities nor does it show the access technology is 5G.  I was wondering  if there was any support  for 5G in MBIM and if anyone was working on it.

# mbimcli -d /dev/cdc-wdm0 --query-device-caps
