ntb_transport_rx_enqueue(9)

✨ NAME ✨

ntb_transport_rx_enqueue — enqueue a new NTB queue entry 💅

okay so this is the ntb_transport_rx_enqueue(9) page from the Kernel API Manual, and it’s literally about sliding a fresh NTB queue entry into place 🦋

🌸 SYNOPSIS 🌸

int ntb_transport_rx_enqueue (struct ntb_transport_qp *qp , void *cb ,
       void *data , unsigned int len );

🎀 ARGUMENTS 🎀

• qp — the NTB transport layer queue that this entry is being enqueued on, no cap
• cb — a per buffer pointer for the callback function to use 👀
• data — pointer to the data buffer where incoming packets get copied into
• len — length of the data buffer

💖 DESCRIPTION 💖

It enqueues a new receive buffer onto the transport queue — the one where an NTB payload can be received into. That’s the whole vibe: new receive buffer, transport queue, NTB payload can land there 💌

🔥 RETURN 🔥

On error you get an appropriate -ERRNO error value; on success you get 0. Slay ✅
