iavf_activate_fdir_filters(9)

💖 iavf_activate_fdir_filters ✨

okay so welcome to the iavf_activate_fdir_filters(9) page bestie — that's the kernel API manual, section 9, and it's literally all about one lil function that does the most iconic post-reset cleanup ever 🎀

---

🌸 NAME 🌸

iavf_activate_fdir_filters — reactivate all the FDIR filters after a reset 👑

yeah. that's the whole job. she comes back after a reset and gets everybody back on their feet 💅

---

✨ SYNOPSIS ✨

void iavf_activate_fdir_filters (struct iavf_adapter *adapter );

like, returns void. doesn't hand anything back. she's not here for credit, she's here for results 🫶

---

🦋 ARGUMENTS 🦋

• adapter — the private adapter structure 💖 that's it, that's the whole argument list. one (1) bestie, and it's the private adapter struct. no cap.

---

🌈 DESCRIPTION 🌈

so here's the vibe: this one gets called after a reset 🔥 and it goes back through and re-adds all FDIR filters — every single one, no filter left behind 😭 — and then it goes and deletes some of them if they were pending to be deleted 💀

so basically: re-add everything, then honor whatever was already queued up for deletion. order matters, the pending-delete girlies don't get forgotten. it's giving "restoration era" honestly ✨

ngl it's a reset-recovery function. if you're calling it and no reset happened, maybe vibe check your call site 🙈 (not me giving advice — that's just what "called after a reset" means, fr fr)
