STRUCT VIRTCHNL2_CONFIG_TX_QUEUES(9)

✨ NAME ✨

struct virtchnl2_config_tx_queues(9) — TX queue config, bestie. Straight from the Kernel API Manual, and it's giving “the PF is about to send a very specific little message about transmit queues.” 💅

🌸 SYNOPSIS 🌸

okay so here's the exact shape, no cap:

struct virtchnl2_config_tx_queues {
    __le32 vport_id;
    __le16 num_qinfo;
    u8 pad[10];
    struct virtchnl2_txq_info qinfo[];
};

🎀 Members 🎀

• vport_id — the Vport id. literally the vport's id, periodt.
• num_qinfo — Number of virtchnl2_txq_info structs. that's the count, bestie.
• pad — Padding. yes, padding. it's just padding, don't overthink it.
• qinfo — Tx queues config info. the actual Tx queue config info, iconic.

💖 Description 💖

Okay so picture this: the PF sends this message to set up parameters for one or more transmit queues. This message contains an array of num_qinfo instances of virtchnl2_txq_info structures. CP configures requested queues and returns a status code.

🚨 warning bestie: if num_qinfo specified is greater than the number of queues associated with the vport, an error is returned and no queues are configured. like, none. zero. the whole request gets no queues. 😭

This whole thing is associated with VIRTCHNL2_OP_CONFIG_TX_QUEUES. iykyk. 🔥
