✨ NAME ✨

okay bestie, welcome to the libnvme(2) glow-up 💖 this page is all about enum nbft_hfi_info_tcp_flags — the HFI Transport Flags, aka the little bitfield that tells you what your HFI (that's Host Fabric Interface, iykyk) is actually up to. 🦋

---

🌸 SYNOPSIS 🌸

enum nbft_hfi_info_tcp_flags {
    NBFT_HFI_INFO_TCP_VALID ,
    NBFT_HFI_INFO_TCP_GLOBAL_ROUTE ,
    NBFT_HFI_INFO_TCP_DHCP_OVERRIDE

};

like… it's giving "three flags, one enum, zero drama" ✨

---

🎀 Constants 🎀

these are the actual flags, and each one is literally just one bit doing its little main character thing 👑

• NBFT_HFI_INFO_TCP_VALID — Descriptor Valid. set it to 1h and this descriptor is valid, like yes it counts, it's real 💅. clear it to 0h and the descriptor is reserved — soz, not your moment babe.
• NBFT_HFI_INFO_TCP_GLOBAL_ROUTE — Global Route vs. Link Local Override Flag 👀. set to 1h? then the BIOS used this interface (the one described by HFI) as the default route with highest priority — she's the main character route, periodt. cleared to 0h? then routes are local to their own scope, very keep-to-yourself energy 🫶.
• NBFT_HFI_INFO_TCP_DHCP_OVERRIDE — DHCP Override 🍓. if it's set to 1, then the HFI information was populated by consuming the DHCP on this interface — she got her info straight from the source, no middleman. cleared to 0h? then the HFI information was set administratively by a configuration interface to the driver and pre-OS envrionment (yep, that's the spelling, not me, I'm just the messenger 😭). so basically: manually configured, not DHCP'd.

no cap, these caveats are load-bearing — a 1h/1 means the thing is ON, and a 0h means it is OFF and you should read what that means for each flag instead of assuming. 💀

there's nothing extra listed here bestie, this page is just the enum and its three constants — short and iconic 🌈

and that's the whole vibe! this lil page lives in the libnvme(2) API Manual, and it was dated July 2026 — shoutout to her for staying on the clock ⭐ byeee, go set some flags responsibly 💜
