✨ SYNOPSIS ✨

int nfp_net_mbox_reconfig (struct nfp_net *nn , u32 mbox_cmd );

🦋 ARGUMENTS 🦋

  • nn — the NFP Net device you're reconfiguring. this is the main character of the whole operation 🫶

🌸 DESCRIPTION 🌸

it's the little guy you call when you need to poke the firmware through its mailbox — nothing flashy, just doing its job so you don't have to. no cap.

negative errno on error, 0 on success. so like, if it comes back negative, something went sideways — read the room (and the errno) 💀
