🌸 NAME 🌸

devlink_fmsg_dump_skb — literally just dumps the sk_buffer structure. that's it. that's the whole job. iconic honestly 💅

---

✨ SYNOPSIS ✨

void devlink_fmsg_dump_skb (struct devlink_fmsg *fmsg , const struct sk_buff *skb );

like, copy-paste it exactly, don't come for me about the spacing, that's how it's written 😭

🎀 ARGUMENTS 🎀

• fmsg — devlink formatted message pointer. this is the message bestie, the one that's gonna carry all the tea 🍓
• skb — pointer to the skb. yes, the actual skb. no cap, you gotta hand it over 🔥

🦋 DESCRIPTION 🦋

so what does it actually do? it dumps diagnostic information about the sk_buff structure — and when I say dump, I mean it's spilling all the details, main character energy only 👑

the stuff it shows you? headroom, length, tailroom, MAC, etc. just… all of it. the whole vibe check on your skb 🌈

ngl, it's giving "here's everything you could possibly want to know about this buffer." obsessed.
