osmo-qcdiag detects CRC errors relatively often
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.
