STRUCT GSM_DLCI_CONFIG(9)

💖 struct gsm_dlci_config(9) 💖

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the page for struct gsm_dlci_config(9), and it's lowkey the blueprint for n_gsm channel configuration. no cap, every field matters. ✨

🌸 NAME 🌸

struct gsm_dlci_config — n_gsm channel configuration parameters.

🦋 SYNOPSIS 🦋

       struct gsm_dlci_config {
           __u32 channel;
           __u32 adaption;
           __u32 mtu;
           __u32 priority;
           __u32 i;
           __u32 k;
           __u32 flags;
           __u32 reserved[7];
        };

🎀 Members 🎀

here's the cast of fields, and yes, they're all main characters:

• channel — DLCI (0 for the associated DLCI).
• adaption — Convergence layer type.
• mtu — Maximum transfer unit.
• priority — Priority (0 for default value).
• i — Frame type (1 = UIH, 2 = UI).
• k — Window size (0 for default value).
• flags — DLCI specific flags.
• reserved — For future use, must be initialized to zero.

quick vibe check: reserved is for future use and must be initialized to zero. don't leave it messy, bestie. 🙈

💅 Description 💅

so this structure teams up with GSMIOC_GETCONF_DLCI and GSMIOC_SETCONF_DLCI to retrieve and set the channel specific parameters of an n_gsm ldisc. it's giving "get and set, but make it channel-specific." periodt. 👑

Set the channel accordingly before calling GSMIOC_GETCONF_DLCI — like, set it first, then call. iykyk. 🌟
