Ohhh, so we just need to add the proper enum entries instead of
flagging them as "reserved" e.g. here:
QMI_DMS_LTE_BAND_CAPABILITY_EUTRAN_24 = 1 << 23,
QMI_DMS_LTE_BAND_CAPABILITY_EUTRAN_25 = 1 << 24,
/* Bit 25-31 reserved */
QMI_DMS_LTE_BAND_CAPABILITY_EUTRAN_33 = ((guint64) 1) << 32,
QMI_DMS_LTE_BAND_CAPABILITY_EUTRAN_34 = ((guint64) 1) << 33,
That's an easy fix, anyone up to doing this easy one? :)
And so we should also probably update the QmiNasActiveBand entry
accordingly as well.
