STRUCT NFP_FLOWER_CMSG_LAG_CONFIG(9)

💖 NAME 💖

struct nfp_flower_cmsg_lag_config — bestie, it's the control message payload for LAG config ✨

So like, this struct is literally the little envelope that carries your LAG (link aggregation, iykyk) configuration around. Main character energy fr.

🌸 SYNOPSIS 🌸

struct nfp_flower_cmsg_lag_config {
    u8 ctrl_flags;
    u8 reserved[2];
    u8 ttl;
    __be32 pkt_number;
    __be32 batch_ver;
    __be32 group_id;
    __be32 group_inst;
    __be32 members[];
};

Periodt. That's the whole layout, no notes 💅

🎀 Members 🎀

Ok so here's the vibe check on every single field, one by one, no skipping (I would never 🙈):

• ctrl_flags — the configuration flags. The ✨flags✨ the flags flags.
• reserved — reserved for future use, so like... hands off, bestie. It's saving that space for later. 🫶
• ttl — time to live of the packet. And ngl, the host always sets this to 0xff. Always. Not a vibe option, it's just what happens. 💀
• pkt_number — the config message packet number. You increment it for each message, okurrr? One message, one bump. 🔥
• batch_ver — batch version of the messages. Increment it for each batch of messages. Batching is iconic, the versioning is mandatory. 👑
• group_id — the group ID applicable. That's the one you want, bestie. 🦋
• group_inst — the group instance number. You increment it when the group is reused. Recycled group? New instance. Slay. ♻️✨
• members — an array of 32-bit words listing all the active group members. Everyone's invited to the party 🎉 (32-bit words only though, no cap).

Quick reminder bestie: that file path is exactly what it is — ./drivers/net/ethernet/netronome/nfp/flower/lag_conf.c — don't go typo-ing it, I'm begging 🙏
