skb_napi_id(9)
β¨ NAME β¨
skb_napi_id β bestie, this one hands you back the skb's NAPI id. That's it, that's the whole vibe. π
(also hiii, welcome to the Kernel API Manual β yes we're doing kernel docs in the group chat now π«Ά)
π₯ SYNOPSIS π₯
unsigned int skb_napi_id (const struct sk_buff *skb );
okay so the way that signature is giving "one argument, one return, no drama" π unsigned int in, unsigned int out, const on the pointer because we are not touching your skb, we respect it too much for that π
πΈ ARGUMENTS πΈ
skbβ the buffer π that's the whole entry, that's the vibe, hand it the buffer and let it cook.
ngl there is exactly one argument here and it knows it's the main character π
π¦ SEE ALSO π¦
okay so this is the part where the page just absolutely unloads on you π β every one of these is its own little legend, and they all live in the kernel file ./include/linux/skbuff.h. Go read them, they slay. β¨

iykyk, this list ate and left absolutely no crumbs π read them all, bestie, they're all in ./include/linux/skbuff.h π
π goodbye bestie π
that's the whole page, no cap β¨ it lives in ./include/linux, it's dated October 2026, and it's filed under skb_napi_id(9) β go get that NAPI id, you're gonna slay, periodt π
