💅 fm10k_sm_mbx_disconnect — Shutdown mailbox connection 💅

okay so bestie, this is the fm10k_sm_mbx_disconnect(9) page from the Kernel API Manual, and it's literally about shutting down a mailbox connection. no cap, it's a lil' cleanup function with main character energy ✨

📛 NAME

fm10k_sm_mbx_disconnect — Shutdown mailbox connection

🧾 SYNOPSIS

void fm10k_sm_mbx_disconnect (struct fm10k_hw *hw , struct
fm10k_mbx_info *mbx );

that's the signature, bestie — don't reformat it, it's giving exact 🫶

🫶 ARGUMENTS

• hw — pointer to hardware structure. yes, the hardware info goes here.
• mbx — pointer to mailbox. the mailbox itself, obvs.

🌸 DESCRIPTION

this function will shut down the mailbox. it places the mailbox first in the disconnect state, then it allows up to a predefined timeout for the mailbox to transition to close on its own. if this does not occur, then the mailbox will be forced into the closed state. periodt 💅

🚨 lowkey important: any mailbox transactions not completed before calling this function are not guaranteed to complete and may be dropped. so don't call it and expect unfinished business to magically finish — it might just get dropped, fr fr 😭
