ice_parse_gtp_type(9)

🦋 ice_parse_gtp_type(9) — Kernel API Manual, bestie edition 🦋

✨ NAME ✨

ice_parse_gtp_type — sets the GTP tunnel type to GTP-U or GTP-C. That’s literally the whole mission, and it ate. 💅

📜 SYNOPSIS 📜

int ice_parse_gtp_type (struct flow_match_ports match , struct
       ice_tc_flower_fltr *fltr );

🎀 ARGUMENTS 🎀

• match — Flow match structure. It’s the matching-info bestie, no cap.
• fltr — Pointer to filter structure. Main-character pointer energy, pointing right at the filter struct. 🫶

💖 DESCRIPTION 💖

Okay so here’s the tea: GTP-C/GTP-U is selected based on the destination port number, aka enc_dst_port. 🌸

Heads up bestie: before you call this function, fltr->tunnel_type should be set to TNL_GTPU.

That makes GTP-U the default choice when the destination port number is not specified. Periodt. 🫶
