💜 devlink_trap_report(9) 💜

okay so bestie, welcome to the devlink_trap_report(9) page — it lives in the Kernel API Manual and it's literally the function that tells drop monitor "hey, we caught a trapped packet 🎀". It's short, it's sweet, it's giving tiny-iconic-manpage energy.

---

✨ NAME ✨

devlink_trap_report — report a trapped packet to drop monitor. that's it, that's the whole gig 🫶

---

🌸 SYNOPSIS 🌸

void devlink_trap_report (struct devlink *devlink , struct sk_buff *skb
, void *trap_ctx , struct devlink_port *in_devlink_port , const struct
flow_action_cookie *fa_cookie );

it returns void, so there's no return value to obsess over. it just does the thing and dips 💅

---

🦋 ARGUMENTS 🦋

five args, all of them matter, let's go one by one:

• devlink — the devlink. yes bestie, that's the whole description. it's the devlink instance you're working with, main character energy 👑
• skb — the trapped packet itself 🍓
• trap_ctx — the trap context ✨
• in_devlink_port — the input devlink port, like the port the packet came in through 🌈
• fa_cookie — the flow action cookie. and listen — this one could be NULL, so don't panic if it is 🙈
