[M] Change in pysim[master]: ts_102_310: Add file definitions resembling ETSI TS 102 310 (EAP)

by laforge

Attention is currently required from: laforge. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/pysim/+/35486?usp=email to look at the new patch set (#4). The following approvals got outdated and were removed: Verified-1 by Jenkins Builder Change subject: ts_102_310: Add file definitions resembling ETSI TS 102 310 (EAP) ...................................................................... ts_102_310: Add file definitions resembling ETSI TS 102 310 (EAP) The definitions are not used yet, as one would have to add that dynamically based on which EF.DIR entries contain the 0x73 discretionary template. As I don't have any cards implementing this so far, I'll skip that part.
