STRUCT NFP_ABM(9)

💖 NAME 💖

struct nfp_abm — the ABM NIC app structure, bestie. that's it, that's the vibe ✨

okay so quick manual-name moment before we dive in: this page lives in the Kernel API Manual, and it's literally all about one struct. buckle up 🎀

---

🦋 SYNOPSIS 🦋

here's the whole thing, character for character, no cap:

struct nfp_abm {
    struct nfp_app *app;
    unsigned int pf_id;
    unsigned int red_support;
    unsigned int num_prios;
    unsigned int num_bands;
    unsigned int action_mask;
    u32 *thresholds;
    unsigned long *threshold_undef;
    u8 *actions;
    size_t num_thresholds;
    unsigned int prio_map_len;
    u8 dscp_mask;
    enum devlink_eswitch_mode eswitch_mode;
    const struct nfp_rtsym *q_lvls;
    const struct nfp_rtsym *qm_stats;
    const struct nfp_rtsym *q_stats;
 };

so many fields. she's giving main character energy 👑

🌸 Members 🌸

okay, field-by-field tour, keep up 🫶

• app — back pointer to nfp_app. yes bestie, it's a back pointer. she points home 🏠
• pf_id — the ID of our PF link 🔗
• red_support — is RED offload supported. short answer: it tells you whether RED offload is supported 💅
• num_prios — number of supported DSCP priorities
• num_bands — number of supported DSCP priority bands 🎶
• action_mask — bitmask of supported actions
• thresholds — current threshold configuration
• threshold_undef — bitmap of thresholds which have not been set. love a bitmap that keeps receipts 🙈
• actions — current FW action configuration
• num_thresholds — number of thresholds and bits in threshold_undef. they match, periodt 💀
• prio_map_len — computed length of FW priority map (in bytes) 📏
• dscp_mask — mask FW will apply on DSCP field
• eswitch_mode — devlink eswitch mode, advanced functions only visible in switchdev mode. read that again: only visible in switchdev mode 👀🔥
• q_lvls — queue level control area
• qm_stats — queue statistics symbol
• q_stats — basic queue statistics (only in per-band case) ⭐

ok one tiny housekeeping note so nothing gets lost: this page is from ./drivers/net/ethernet/netrono... and it's dated October 2026 📅

k that's the whole struct, go slay your networking, bestie 💜🌈💅
