Description

Irrespective of the baud rate used, and even without too much DIAG activity, osmo-qcdiag detects CRC errors of the DIAG frames. This is odd, particularly as the framing code is taken from the Qualcomm Linux Kernel DIAG subsystem, i.e. it is from Qualcomm themselves.

I'm not sure when that happens, but let's try to narrow this down furher by looking at the actual frames in question.

Interestingly, this happens a lot with EC20/EC25, but doesn't happen at all when using a Gobi2000 device. So it might be something specific (and/or broken) in Quectel EC2x?
