Public bug reported:
The modemmanager debian package in focal was recently upgraded to 1.18
(apparently the jammy version was backported). This version has broken
some Qualcomm modems as it start to require the Qualcomm IPC Router for
them, which drivers are not enabled in Ubuntu kernel 5.4. To fix this we
need these options enabled in the focal kernel:
CONFIG_QRTR=m
CONFIG_QRTR_SMD=m
CONFIG_QRTR_TUN=m
CONFIG_QRTR_MHI=m
The options are already enabled in more modern Ubuntu kernel, i.e. 5.17.
