i40e_aq_set_switch_config(9)

✨ NAME ✨

i40e_aq_set_switch_config</p> — and bestie, that's literally it. The original page just trails off after the dash, no tagline, no nothing. The audacity. 💀

This is page 9 of the Kernel API Manual, so pull up a chair, we're doing Intel NIC lore today. 🧚

---

🌸 SYNOPSIS 🌸

okay so here's the whole vibe, copied character for character because I would simply never mess with your sig:

int i40e_aq_set_switch_config (struct i40e_hw *hw , u16 flags , u16
valid_flags , u8 mode , struct i40e_asq_cmd_details *cmd_details );

that's a return int, five arguments, and yes the line break in the middle is exactly where upstream put it. periodt. 💅

---

🎀 ARGUMENTS 🎀

the whole squad, one by one:

• hw — pointer to the hardware structure. your actual NIC's lil soul, the thing you're talking to. 🫶
• flags — bit flag values to set. these are the bits you actually want flipped on.
• valid_flags — which bit flags to set. like, of all the bits in flags, this is the mask telling the hardware which of them it's allowed to look at. iykyk.
• mode — cloud filter mode. yes it's a u8, yes it's about cloud filters.
• cmd_details — pointer to command details structure or NULL. NULL is a totally valid answer here, no cap.

🦋 DESCRIPTION 🦋

Set switch configuration bits

that's. it. that's the description. one line. the manpage really said "I said what I said" and dipped. 😭

so like, the way that this tells you everything and nothing at the same time? iconic honestly. the flags + valid_flags combo is the bits, mode is the cloud filter mode, and cmd_details rides along or is just NULL if you're low-maintenance. go off, king. 👑

okay so this is the part where the page goes absolutely feral and name-drops the entire friend group. like genuinely, this is a group chat with 127 members and nobody has muted notifications. here we go, in order, no skips:

so anyway, that's the page 💜 it lives in ./drivers/net/ethernet/intel/i40e, and it was stamped October 2026 — go forth and set those switch configuration bits, bestie, you've got this fr fr ✨🎀🦋
