iavf_parse_r...ow_user_data(9)

🌸 iavf_parse_rx_flow_user_data — a Kernel API Manual moment (section 9, bestie) 🌸

okay so real talk, we're in the Kernel API Manual today and the star of the show is iavf_parse_rx_flow_user_data. yes the header truncates it to iavf_parse_r...ow_user_data(9) — that's just the terminal being dramatic and running out of room, the actual name is not abbreviated, i promise 🫶

✨ NAME ✨

iavf_parse_rx_flow_user_data — deconstruct user-defined data 💅

like, it takes the user-defined stuff apart. deconstruction. very main character.

---

✨ SYNOPSIS ✨

int iavf_parse_rx_flow_user_data (struct ethtool_rx_flow_spec *fsp ,
struct iavf_fdir_fltr *fltr );

two pointers, one int return, that's the whole vibe 🦋

---

✨ ARGUMENTS ✨

• fsp — pointer to ethtool Rx flow specification. it's the flow spec, she's holding the Rx flow info 🎀
• fltr — pointer to Flow Director filter for userdef data storage. this is where the user-defined data gets stored, no cap 💖

---

✨ DESCRIPTION ✨

Returns 0 on success, negative error value on failure. that's it. that's the whole description. short and iconic, honestly 👑

lowkey a serve that the description is one line. not every function needs a monologue.

🎀 the cute lil sign-off 🎀

this page lives in ./drivers/net/ethernet/intel/iavf — that's the directory, that's the home base 🏠 and it's dated October 2026, so yeah, she's from the future, we love a forward-thinking queen ⭐

mwah, go read iavf_ethtool.c, drink some water, and remember: 0 on success, negative on failure 💖✨
