STRUCT NFP_ABM_LINK(9)

🌸 struct nfp_abm_link(9) 🌸

okay bestie, welcome to the Kernel API Manual — yes it's a real manual-page situation and yes we're gonna make it cute 💅 this one's all about struct nfp_abm_link, which is literally the port tuple of a ABM NIC. iconic little container, no cap 🎀

✨ NAME ✨

struct nfp_abm_link — port tuple of a ABM NIC 🦋

✨ SYNOPSIS ✨

struct nfp_abm_link {
    struct nfp_abm *abm;
    struct nfp_net *vnic;
    unsigned int id;
    unsigned int queue_base;
    unsigned int total_queues;
    u64 last_stats_update;
    u32 *prio_map;
    bool has_prio;
    u8 def_band;
    struct list_head dscp_map;
    struct nfp_qdisc *root_qdisc;
    struct radix_tree_root qdiscs;
 };

✨ Members ✨

the way this struct has so many members… main character energy fr fr 👑

• abm — back pointer to nfp_abm. it's giving "find your way home" 🏠
• vnic — the data vNIC. hi bestie 👋
• id — id of the data vNIC. short, simple, slays ✨
• queue_base — id of base to host queue within PCIe (not QC idx). and yes, not QC idx — clock that, it matters 💀
• total_queues — number of PF queues. counting them all, obsessed 🔢
• last_stats_update — ktime of last stats update. literally a timestamp glow-up 🕐
• prio_map — current map of priorities. current being the key word 🗺️
• has_prio — prio_map is valid. it's the vibe check for the map above 😌
• def_band — default band to use. the default! the fallback! the understudy that ate 🌈
• dscp_map — list of DSCP to band mappings. mapping era 💖
• root_qdisc — pointer to the current root of the Qdisc hierarchy. root of the tree, queen of the hill 👑
• qdiscs — all qdiscs recorded by major part of the handle. every single one, no crumbs left 🍓
