i40e_fill_rx_flow_user_data(9)

💅 i40e_fill_rx_flow_user_data(9) 💅

okay so bestie, this is a page from the Kernel API Manual and it's all about one lil' helper function in the Intel i40e driver. she's small, she's tidy, she does exactly one thing, and honestly? we stan a focused queen 👑

---

✨ NAME ✨

i40e_fill_rx_flow_user_data — fills in the user-defined data field 🫶

---

🎀 SYNOPSIS 🎀

void i40e_fill_rx_flow_user_data (struct ethtool_rx_flow_spec *fsp ,
       struct i40e_rx_flow_userdef *data );

like, that's it. two pointers, no return value, no drama. void said "i'm not giving you anything back and that's on periodt" 💀

---

🌸 ARGUMENTS 🌸

• fsp — pointer to the rx_flow specification, aka the glow-up target 💖
• data — pointer to the return userdef data, aka where the good stuff gets read from

---

🦋 DESCRIPTION 🦋

so the way that this works is: it reads the userdef data structure and then properly fills in the user-defined fields of the rx_flow_spec. that's the whole vibe check. reads one struct, populates the other, no cap. ✨
