STRUCT IDPF_NETDEV_PRIV(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual page for struct idpf_netdev_priv(9) — literally the struct to store vport back pointer. that’s the whole vibe: a lil’ struct holding the vport back pointer, and we’re about to meet every member like it’s a group-chat roll call 💅✨

✨ SYNOPSIS ✨

here’s the struct in all its glory, no cap — copy it exactly because this is the real shape:

       struct idpf_netdev_priv {
           struct idpf_adapter *adapter;
           struct idpf_vport *vport;
           u32 vport_id;
           u32 link_speed_mbps;
           u16 vport_idx;
           u16 max_tx_hdr_size;
           u16 tx_max_bufs;
           unsigned long state[BITS_TO_LONGS( IDPF_VPORT_STATE_NBITS)];
           struct rtnl_link_stats64 netstats;
           spinlock_t stats_lock;
        };

💅 Members 💅

okay so let’s do the member-by-member vibe check. every field is iconic in its own way 🫶

• adapter — adapter back pointer. lowkey the adapter’s back-pointer bestie.
• vport — vport back pointer. yes, another back pointer, and it’s serving.
• vport_id — vport identifier. the ID card for the vport, fr fr.
• link_speed_mbps — link speed in mbps. the link speed, in mbps, exactly as advertised 💫
• vport_idx — relative vport index. relative, bestie — not absolute.
• max_tx_hdr_size — max header length hardware can support. the hardware has a max header length and this field is literally holding that info 😭
• tx_max_bufs — max buffers that can be transmitted with scatter-gather. scatter-gather said “how many buffers?” and this is the answer.
• state — see enum idpf_vport_state. that’s the reference, no extra lore.
• netstats — packet and byte stats. packets, bytes, stats — the whole cute data moment.
• stats_lock — lock to protect stats update. gotta protect that stats update, periodt 🔒
