ENUM NFP_MBOX_CMD(9)

🎀 enum nfp_mbox_cmd(9) 🎀

okay bestie, so this is a Kernel API Manual page for enum nfp_mbox_cmd and it's literally all about PF mailbox commands — like, the little message slips the PF passes around 💌

✨ NAME ✨

enum nfp_mbox_cmd — PF mailbox commands 💅

🌸 SYNOPSIS 🌸

enum nfp_mbox_cmd {
    NFP_MBOX_NO_CMD ,
    NFP_MBOX_POOL_GET ,
    NFP_MBOX_POOL_SET ,
    NFP_MBOX_PCIE_ABM_ENABLE ,
    NFP_MBOX_PCIE_ABM_DISABLE

};

like, that's the whole enum, no cap 🫶

🌈 CONSTANTS 🌈

• NFP_MBOX_NO_CMD — the null command. it's giving "nothing to see here" energy, and it's used to indicate that the previous command has finished ✅
• NFP_MBOX_POOL_GET — get the shared buffer pool info/config. Input — struct nfp_shared_buf_pool_id Output — struct nfp_shared_buf_pool_info_get
• NFP_MBOX_POOL_SET — set the shared buffer pool info/config. Input — struct nfp_shared_buf_pool_info_set Output — None
• NFP_MBOX_PCIE_ABM_ENABLE — enable PCIe-side advanced buffer management. this one enables advanced buffer management of the PCIe block. and listen, if ABM is disabled the PCIe block maintains a very short queue of buffers and does tail drop 😭 ABM is the glow-up: it allows more advanced buffering and priority control 💖 Input — None Output — None
• NFP_MBOX_PCIE_ABM_DISABLE — disable PCIe-side advanced buffer management. Input — None Output — None

k that's the whole page, you ate that 🍓 this one lives over in ./drivers/net/ethernet/netrono... (yes it's truncated in the original, not me being lazy 💀) and it's dated October 2026. mwah, go read the ABI header bestie 🧚‍♀️💜
