STRUCT MACSEC_TX_SC(9)

🌸 NAME 🌸

okay so welcome to the struct macsec_tx_sc(9) page from the Kernel API Manual — we're talking about the transmit secure channel, and it's lowkey iconic in a deeply kernel-specific way 💅✨.

struct macsec_tx_sc — transmit secure channel 🦋 — that's the whole NAME vibe, bestie.

✨ SYNOPSIS ✨

here's the struct, bestie — copy the fields exactly, no freestyling:

       struct macsec_tx_sc {
           bool active;
           u8 encoding_sa;
           bool encrypt;
           bool send_sci;
           bool end_station;
           bool scb;
           struct macsec_tx_sa *sa[MACSEC_NUM_AN];
           struct pcpu_tx_sc_stats __percpu *stats;
           struct metadata_dst *md_dst;
        };

🎀 Members 🎀

member-by-member, no skips, periodt 👑:

• active — just active in the source, no extra description attached; we're not inventing lore 🙈.
• encoding_sa — association number of the SA currently in use.
• encrypt — encrypt packets on transmit, or authenticate only.
• send_sci — always include the SCI in the SecTAG.
• end_station — listed with no description in the source, so it's giving mysterious main character energy 👀.
• scb — single copy broadcast flag.
• sa — array of secure associations.
• stats — stats for this TXSC.
• md_dst — MACsec offload metadata dst.

💫 SEE ALSO 💫

bestie, for more kernel lore, the kernel file is ./include/net/macsec.h, and the whole referenced squad is:

• struct macsec_key(9)
• struct macsec_rx_sa(9)
• struct macsec_rx_sc(9)
• struct macsec_tx_sa(9)
• struct macsec_secy(9)
• struct macsec_context(9)
• struct macsec_ops(9)
