✨ enum vfdi_op(9) ✨

okay so bestie, welcome to the Kernel API Manual page for enum vfdi_op — literally the VFDI operation enumeration, and yes we're gonna get into all of it 💅

🦋 NAME 🦋

enum vfdi_op — the VFDI operation enumeration, bestie. that's the whole vibe.

🌸 SYNOPSIS 🌸

enum vfdi_op {
    VFDI_OP_RESPONSE ,
    VFDI_OP_INIT_EVQ ,
    VFDI_OP_INIT_RXQ ,
    VFDI_OP_INIT_TXQ ,
    VFDI_OP_FINI_ALL_QUEUES ,
    VFDI_OP_INSERT_FILTER ,
    VFDI_OP_REMOVE_ALL_FILTERS ,
    VFDI_OP_SET_STATUS_PAGE ,
    VFDI_OP_CLEAR_STATUS_PAGE ,
    VFDI_OP_LIMIT

};

look at her. all those constants lined up like a little squad 🫶

🎀 Constants 🎀

• VFDI_OP_RESPONSE — it's giving "this is a reply to the request", yep, that's the whole job. she responds 💬
• VFDI_OP_INIT_EVQ — initializes the SRAM entries AND initializes an EVQ. two for one, iconic ✨
• VFDI_OP_INIT_RXQ — initializes the SRAM entries and initializes an RXQ. same energy, receive flavored 🍓
• VFDI_OP_INIT_TXQ — initializes the SRAM entries and initializes a TXQ. transmit era 💅
• VFDI_OP_FINI_ALL_QUEUES — flushes all the queues, finalizes all the queues, then finalizes the SRAM entries. it's a whole closer, main character energy 👑
• VFDI_OP_INSERT_FILTER — inserts a MAC filter that targets the given RXQ. targeted. precise. slay 🎯
• VFDI_OP_REMOVE_ALL_FILTERS — removes all the filters. not some. all. periodt 💀
• VFDI_OP_SET_STATUS_PAGE — sets the DMA page(s) used for status updates from PF, and writes the initial status. setting the stage AND writing the first line 🎬
• VFDI_OP_CLEAR_STATUS_PAGE — clears the DMA page(s) used for status updates from PF. bye bye status page 👋
• VFDI_OP_LIMIT — -- undescribed -- 😭 no cap, the docs literally left her undescribed. she's a mystery, we love that for her 🙈
