Description

This also relates to this error seen with EGPRS capable phone:
"Not accepting non-EGPRS phone in EGPRS-only mode"

However, in GPRS mode, this does not appear to make any immediately obvious difference to functionality, but all the same, MS_CLASS=0/0 is obviously wrong.

This is because the code to parse the MS RA Cap is commented, with a note:

"Do not rely on this IE."

As far as I can tell from analysis of NS trace, the BSSGP contains correct Radio Access Capability IE, that is to say, It is corresponding with what the MS sent in the Attach Request.

So why "do not rely?" Why is the code commented? Perhaps in 2016, this information from the BSSGP was not reliable?

See http://git.osmocom.org/osmo-pcu/commit/?id=741d25cb6f8c0c1522cf6d1be2fea49356ecd4bd
and the two previous commits.
