💖 fm10k_mbx_validate_msg_size(9) 💖

okay so bestie, welcome to the Kernel API Manual page for fm10k_mbx_validate_msg_size(9) — yes the name is a whole mouthful, yes it ate, stay with me 🌈

---

✨ NAME ✨

fm10k_mbx_validate_msg_size — validate incoming message based on size 🎀

🌸 SYNOPSIS 🌸

u16 fm10k_mbx_validate_msg_size (struct fm10k_mbx_info *mbx , u16 len );

🎀 ARGUMENTS 🎀

• mbx — pointer to mailbox 🫶
• len — length of data pushed onto buffer

💅 DESCRIPTION 💅

So this function is basically the vibes checker for an incoming frame — it analyzes the frame, and it will return a non-zero value when it detects the start of a message that's larger than the mailbox. That's the whole gig. Non-zero is your little "girl, that's too much" signal, iykyk 💀

no cap, that's the entire description in the original — it's short and iconic like that 🔥
