ENUM IONIC_PORT_FEC_TYPE(9)

💅 enum ionic_port_fec_type(9) 💅

okay bestie, so we're deep in the Kernel API Manual today — this is the ionic driver's very own enum, the one that lists out your Ethernet Forward error correction (FEC) modes ✨. yes, FEC. the thing that saves your packets when the cable's having a bad day. we love her. 🫶

🦋 SYNOPSIS 🦋

enum ionic_port_fec_type {
    IONIC_PORT_FEC_TYPE_NONE ,
    IONIC_PORT_FEC_TYPE_FC ,
    IONIC_PORT_FEC_TYPE_RS

};

no cap, that's the whole shape of it — three members, and then a lil trailing blank line before the closing brace because the kernel headers simply vibe that way 💀

---

🌸 CONSTANTS 🌸

bestie, there are literally three of them and each one is a different flavour of "how do we correct these errors":

• IONIC_PORT_FEC_TYPE_NONE — FEC Disabled. like, we're raw-dogging the wire. no error correction, no safety net, just vibes and hope 🙈
• IONIC_PORT_FEC_TYPE_FC — FireCode FEC. FireCode!! iconic name, honestly. 🔥
• IONIC_PORT_FEC_TYPE_RS — ReedSolomon FEC. the classic, the legend, the mathematically blessed one 👑

that's it. that's the enum. short, sweet, three members deep. iykyk ✨

🎀 SEE ALSO 🎀

okay so this is the part where the manpage goes absolutely feral and lists the entire ionic header in one breath. buckle up, we're going through all of it, no skipping, no summarising, periodt 💅

like… that's a lot of cross-references and honestly? iconic of the ionic_if.h header to have that much going on. main character energy fr fr 💜

🫶 quick reminder bestie: this page is documentation for the kernel's own reference — reading it doesn't change any hardware. if you actually mess with FEC settings, make sure you know which mode your gear supports before you go poking at IONIC_PORT_FEC_TYPE_RS like it's nothing. 🌈

and that's the whole page!! came from ./drivers/net/ethernet/pensand... and it's dated October 2026, tagged enum ionic_port_fec_type(9) — so if you're quoting her in a commit message or a bug report, that's the whole citation. slay, go forth and correct some forward errors, mwah 💖🎀✨
