STRUCT IDPF_VPORT(9)

🦋 struct idpf_vport(9) — the Kernel API Manual moment 💅

okay so this is a page from the Kernel API Manual, and honestly? it's giving main character energy for a struct. buckle up bestie, we're meeting struct idpf_vport 🎀

✨ NAME ✨

struct idpf_vport — the handle for netdevices and queue resources. that's it, that's the vibe. it's the little container that holds all the stuff your vport needs 🫶

🌸 SYNOPSIS 🌸

struct idpf_vport {
    struct idpf_q_vec_rsrc dflt_qv_rsrc;
    struct idpf_tx_queue **txqs;
    u16 num_txq;
    u16 num_xdp_txq;
    bool xdpsq_share;
    struct bpf_prog *xdp_prog;
    struct iidc_rdma_vport_dev_info *vdev_info;
    struct idpf_adapter *adapter;
    struct net_device *netdev;
    unsigned long flags[BITS_TO_LONGS( IDPF_VPORT_FLAGS_NBITS)];
    u32 compln_clean_budget;
    u32 vport_id;
    u16 vport_type;
    u16 idx;
    u16 max_mtu;
    u8 default_mac_addr[ETH_ALEN];
    u16 rx_itr_profile[IDPF_DIM_PROFILE_SLOTS];
    u16 tx_itr_profile[IDPF_DIM_PROFILE_SLOTS];
    struct idpf_port_stats port_stats;
    bool default_vport;
    bool crc_enable;
    bool link_up;
    struct idpf_ptp_vport_tx_tstamp_caps *tx_tstamp_caps;
    struct kernel_hwtstamp_config tstamp_config;
    struct work_struct tstamp_task;
    struct idpf_tstamp_stats tstamp_stats;
 };

like, look at that. every field is literally a little icon in the group chat 💖

👑 Members 👑

• dflt_qv_rsrc — holds the default queue and vector resources. the starter pack, if you will ✨
• txqs — used only in hotpath to get to the right queue super duper fast ⚡ no cap, speed matters here.
• num_txq — the number of allocated TX queues.
• num_xdp_txq — how many XDPSQs there are.
• xdpsq_share — tells you whether XDPSQ sharing is enabled. yes/no situation 🔥
• xdp_prog — the installed XDP program.
• vdev_info — the IDC vport device info pointer.
• adapter — a back pointer to the associated adapter. it knows where it came from 🧚
• netdev — the associated net_device. important lore: each vport should have one and only one associated netdev. periodt 💅
• flags — see enum idpf_vport_flags.
• compln_clean_budget — the work budget for completion clean. budget queen 🎀
• vport_id — the device-given vport identifier.
• vport_type — default SRIOV, SIOV, etc. pick your fighter 🌈
• idx — the software index in the adapter vports struct.
• max_mtu — the device-given max possible MTU. like, the ceiling, fr fr.
• default_mac_addr — the device will give a default MAC to use. cute little hand-me-down address 🍓
• rx_itr_profile — RX profiles for Dynamic Interrupt Moderation.
• tx_itr_profile — TX profiles for Dynamic Interrupt Moderation. twins!! 👯
• port_stats — per port csum, header split, and other offload stats. the receipts 📊
• default_vport — use this vport if one isn't specified. the fallback bestie 🫶
• crc_enable — enable CRC insertion offload.
• link_up — true if link is up. and if it's not... well 😭
• tx_tstamp_caps — the capabilities negotiated for Tx timestamping.
• tstamp_config — the Tx tstamp config.
• tstamp_task — the Tx timestamping task.
• tstamp_stats — Tx timestamping statistics. numbers go brrr ⭐
