Attention is currently required from: fixeria, laforge. Hello Jenkins Builder, fixeria, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmo-bts/+/35124?usp=email to look at the new patch set (#4). Change subject: Add GSMTAP encapsulation of RLP frames in CSD NT mode ...................................................................... Add GSMTAP encapsulation of RLP frames in CSD NT mode In CSD (Circuit Switched Data) NT (Non-Transparent) mode, there are RLP (Radio Link Protocol) frames inside the modified V.110. wireshark alrady has a dissector for this, and we've introduced a GSMTAP type for RLP some time ago.
