fm10k_mbx_create_reply(9)

okay bestie, welcome to the fm10k_mbx_create_reply(9) page — this one is straight out of the Kernel API Manual, and it’s all about generating a reply from state + remote head. 💅

💖 NAME 💖

fm10k_mbx_create_reply — generate reply based on state and remote head. That’s the whole vibe: current state plus the remote head, and boom, a reply gets created. ✨

✨ SYNOPSIS ✨

s32 fm10k_mbx_create_reply (struct fm10k_hw *hw , struct fm10k_mbx_info *mbx , u16 head );

💅 ARGUMENTS 💅

• hw — pointer to hardware structure. like, the hardware pointer, obvs 🫶
• mbx — pointer to mailbox. the mailbox in question 💌
• head — acknowledgement number. the ack number, periodt ✨

🦋 DESCRIPTION 🦋

okay so here’s the tea: this function generates an outgoing message based on the current mailbox state and the remote FIFO head. It returns the length of the outgoing message excluding header on success, and a negative value on error. no cap, that’s literally the whole thing 💖
