ice_flow_add_entry(9)

💖 ice_flow_add_entry — the "add a flow entry" girlies 💖

Okay so bestie, welcome to the Kernel API Manual for ice_flow_add_entry(9). Yes, section 9, we love a kernel-internals moment. Sit down, grab a strawberry drink 🍓, and let's get into it.

---

✨ NAME ✨

ice_flow_add_entry — literally just Add a flow entry. That's the whole vibe. No cap.

---

🦋 SYNOPSIS 🦋

int ice_flow_add_entry (struct ice_hw *hw , enum ice_block blk , u64
prof_id , u64 entry_id , u16 vsi_handle , enum ice_flow_priority prio ,
void *data , u64 *entry_h );

She takes a whole friend group of arguments and returns an int. Periodt. 💅

---

🎀 ARGUMENTS 🎀

Every single one of them, in order, because we do not skip the boring parts in this house:

• hw — pointer to the HW struct. The hardware bestie herself. 🫶
• blk — classification stage. Which stage are we at, iykyk.
• prof_id — ID of the profile to add a new flow entry to. The profile we're sliding into. ✨
• entry_id — unique ID to identify this flow entry. Unique! Don't reuse it, that's not the vibe. 🙈
• vsi_handle — software VSI handle for the flow entry. Your lil software-side handle.
• prio — priority of the flow entry. <italic>enum ice_flow_priority</italic>, very demure, very mindful.
• data — pointer to a data buffer containing flow entry's match values/masks. The matchy-matchy bits go here. 🎯
• entry_h — pointer to buffer that receives the new flow entry's handle. She's an output, bestie — the new handle lands here. Lowkey the most important one. 👑

Heads up: data holds the match values AND masks, and entry_h is where the new handle gets written. Those are the two you'll be staring at while debugging at 2am, trust. 😭
