STRUCT IDPF_VPORT_USER_CONFIG_DATA(9)

💅 struct idpf_..._config_data(9) 💅

okay bestie, so this is a page straight out of the Kernel API Manual and it's genuinely iconic — it's the struct where a vport keeps all its user-defined configuration values. One of these per vport, no cap. 🫶

---

✨ NAME ✨

struct idpf_vport_user_config_data — the user defined configuration values for each vport. That's it, that's the whole vibe. 💖

---

🌸 SYNOPSIS 🌸

struct idpf_vport_user_config_data {
    struct idpf_rss_data rss_data;
    struct idpf_q_coalesce *q_coalesce;
    u16 num_req_tx_qs;
    u16 num_req_rx_qs;
    u32 num_req_txq_desc;
    u32 num_req_rxq_desc;
    struct bpf_prog *xdp_prog;
    unsigned long user_flags[BITS_TO_LONGS( __IDPF_USER_FLAGS_NBITS)];
    struct list_head mac_filter_list;
    u32 num_fsteer_fltrs;
    struct list_head flow_steer_list;
        };

like. look at her. she's holding SO much. 👑

🎀 Members 🎀

• rss_data — head over to struct idpf_rss_data for the details, iykyk.
• q_coalesce — an array of per queue coalescing data. one for each queue, she's not playing favorites. ✨
• num_req_tx_qs — the number of TX queues the user requested through ethtool.
• num_req_rx_qs — the number of RX queues the user requested through ethtool.
• num_req_txq_desc — the number of TX queue descriptors the user requested through ethtool.
• num_req_rxq_desc — the number of RX queue descriptors the user requested through ethtool.
• xdp_prog — the requested XDP program to install. 🦋
• user_flags — the user toggled config flags. main character energy fr.
• mac_filter_list — the list of MAC filters.
• num_fsteer_fltrs — the number of flow steering filters.
• flow_steer_list — the list of flow steering filters.

💜 Description 💜

So what's she for? She's used to restore configuration after a reset, because otherwise the vport will get wiped 😭. That's the whole reason she exists — the vport gets absolutely obliterated on reset, and this struct is the one holding the receipts so everything can come back. periodt. 💀
