🎀 NAME 🎀

okay so first things first: this page lives in the Kernel API Manual, and it's literally called fm10k_mbx_dequeue_rx(9) 💅

like, it reaches into the Rx FIFO and yoinks the message sitting at the head. first in line? first out bestie ✨

🌸 SYNOPSIS 🌸

u16 fm10k_mbx_dequeue_rx (struct fm10k_hw *hw , struct fm10k_mbx_info
*mbx );

💖 ARGUMENTS 💖

• hw — pointer to hardware structure, the actual hardware vibes 🫶
• mbx — pointer to mailbox, the mailbox in question 💌

✨ DESCRIPTION ✨

so the way that this works is: this function dequeues messages and hands them off to the TLV parser 🎀 like a little relay race, except the baton is a message and the finish line is the parser.

and when you call it, it will return the number of messages processed. that's the count, that's the receipt, that's the "how many did I just get through" number fr fr 🔥
