t4vf_enable_vi(9)

💅 t4vf_enable_vi — the Kernel API Manual, section 9, bestie ✨

Okay so picture this: you're deep in section 9 of the Kernel API Manual and you need to flip a virtual interface on or off. That's it. That's the whole gig. Her name is t4vf_enable_vi, she's iconic, and she's about to make your whole networking afternoon 💖

✨ NAME ✨

t4vf_enable_vi — enable/disable a virtual interface 🎀

Like, she does both?? A dual-threat queen. One call, two directions, zero drama (unless you count the mailbox stuff, which, lowkey, we'll get to in SEE ALSO 👀).

---

🌸 SYNOPSIS 🌸

int t4vf_enable_vi (struct adapter *adapter , unsigned int viid , bool
       rx_en , bool tx_en );

She returns an int, she takes four args, and yes the signature is doing that little line-wrap thing where bool sits by itself at the end of a line. Not me being weird about it — that's literally how it's printed. Copy it exactly, bestie, fr fr 💅

---

🦋 ARGUMENTS 🦋

• adapter — the adapter 🫶 like, the whole device situation you're working with
• viid — the Virtual Interface ID ✨ the specific VI you're pointing at, no cap
• rx_en — 1=enable Rx, 0=disable Rx 📥 the receive switch, literally a one or a zero, that's the whole vibe
• tx_en — 1=enable Tx, 0=disable Tx 📤 the transmit switch, same deal, 1 on / 0 off

---

💜 DESCRIPTION 💜

Enables/disables a virtual interface. 🌈

That's it. That's the tweet. You give her the adapter, you tell her which VI, you say whether Rx is a yes or a no, you say whether Tx is a yes or a no, and she goes and does the thing. Two booleans, four combinations, infinite main character energy 👑

Ngl the description is short because the manpage is short. I'm not gonna sit here and invent lore that isn't in the source — that would be lying, and lying is not slay 🙈

Thirty-four friends and every single one of them got an invite 🎀 not a single one skipped, periodt.

🌷 the cute lil sign-off 🌷

This page came straight out of ./drivers/net/ethernet/chelsio... (that's the source/version bit, they truncate it with the lil dots and honestly same, my bio is truncated too 😭) and it's dated October 2026 — yes, the future, she's ahead of her time, she's giving time-travel icon 🕰️✨

Mwah, go enable a virtual interface, you've got this 💖🌸🦋
