ice_flow_add_prof_sync(9)

💖 ice_flow_add_prof_sync(9) — like, the kernel API manual bestie ✨

Okay so we're deep in the ice driver pages of the kernel API manual, and this one is all about adding a flow profile for packet segments and fields. Yes, that's the NAME section, and yes, it ate. 🌸

---

✨ SYNOPSIS ✨

int ice_flow_add_prof_sync (struct ice_hw *hw , enum ice_block blk ,
       enum ice_flow_dir dir , struct ice_flow_seg_info *segs , u8 segs_cnt ,
       bool symm , struct ice_flow_prof **prof );

She returns an int, she takes seven args, she's that girl. 💅

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW struct. Your hardware baddie, the main character of this whole operation 👑
• blk — classification stage. Which stage of the pipeline we're playing in fr
• dir — flow direction. Which way the packets are going, no cap 🦋
• segs — array of one or more packet segments that describe the flow. Literally the packet bits you care about, listed out 💜
• segs_cnt — number of packet segments provided. Gotta tell it how long that array is, iykyk
• symm — symmetric setting for RSS profiles. The symmetry vibe check 🌈
• prof — stores the returned flow profile added. This is where the shiny new profile lands, obsessed 😭

---

💀 DESCRIPTION 💀

Assumption: the caller has acquired the lock to the profile list.

Yeah that's the whole description and it's not a suggestion bestie — the caller has to have already grabbed the lock on the profile list before calling this. No lock, no service. Periodt. 🔥
