💖 NAME 💖

struct nvme_fabrics_config — the lil struct that holds every single linux nvme fabrics initiator option, no cap. It's literally the master list of all your connection vibes. ✨

🦋 SYNOPSIS 🦋

Bestie. Look at her. She's gorgeous:

struct nvme_fabrics_config {
    char *host_traddr;
    char *host_iface;
    int queue_size;
    int nr_io_queues;
    int reconnect_delay;
    int ctrl_loss_tmo;
    int fast_io_fail_tmo;
    int keep_alive_tmo;
    int nr_write_queues;
    int nr_poll_queues;
    int tos;
    long keyring;
    long tls_key;
    long tls_configured_key;
    bool duplicate_connect;
    bool disable_sqflow;
    bool hdr_digest;
    bool data_digest;
    bool tls;
    bool concat;
 };

Not me counting the fields like it's a roster 😭 twenty whole members, every one of them a main character.

🌸 Members 🌸

Okay so here's the whole squad, field by field. Every one matters, iykyk. 💅

• host_traddr — the host transport address. Where you're coming from, bestie. 🫶
• host_iface — the host interface name. Which network face you're showing the world. ✨
• queue_size — number of IO queue entries. Yes, the size of the queue. It's giving capacity. 📦
• nr_io_queues — how many controller IO queues to actually establish. How many lanes you're opening up. 🔥
• reconnect_delay — the time between two consecutive reconnect attempts. Note the period at the end of that one, it's the original's period, I'm keeping it, do not perceive me. 😭
• ctrl_loss_tmo — override the default controller reconnect attempt timeout, in seconds. You get to pick how long you're willing to wait before giving up on the controller. Patient queen energy. 👑
• fast_io_fail_tmo — set the fast I/O fail timeout, in seconds. Fast fail. Fail fast. Become the fail. 💀
• keep_alive_tmo — override the default keep-alive-timeout to this value, in seconds. Yes it's a "keep-alive". Yes it's keeping the connection alive. We love a supportive field. 💖
• nr_write_queues — number of queues to use for exclusively for writing. (The grammar there is the original's, I'm just the messenger 💅) Write-only queues. No reading. Reading is not their job. 🙈
• nr_poll_queues — number of queues to reserve for polling completions. Reserved. Set aside. Special little guys. ⭐
• tos — type of service. The classic. The icon. 🌈
• keyring — keyring to store and lookup keys. Where the secrets live. 🔐
• tls_key — the TLS PSK for the connection. 🔑
• tls_configured_key — the TLS PSK for connect command for the connection. Yes, a second, different PSK. They are not the same. Do not merge them in your head, bestie, I'm serious. 😤
• duplicate_connect — allow multiple connections to the same target. Why not, honestly. Slay. 🎀
• disable_sqflow — disable controller sq flow control. Off. Gone. Bye. ✂️
• hdr_digest — generate/verify header digest, TCP only. ✅
• data_digest — generate/verify data digest, TCP only. ✅
• tls — start TLS on the connection, TCP only. 🔒✨
• concat — enable secure concatenation, TCP only. 🧚

Heads up bestie: the last four? All TCP. Don't come for me if you're on a different transport and they're feeling unbothered. That's just what the page says. 🫶

And that's the whole struct, every last field, exactly as documented, no notes. Go forth and configure your fabrics. ✨

bye bestie, love u, read the field docs 💜
