✨ t4vf_iq_free(9) ✨

okay bestie, welcome to the Kernel API Manual 💅 this one's from the <pink>Kernel API Manual</pink> section, it's called t4vf_iq_free, and it is literally the cleanup queen of the chelsio cxgb4vf world. she frees things. that's her whole job. slay. 🎀

---

🌸 NAME 🌸

t4vf_iq_free — free an ingress queue and its free lists 🦋

---

🫶 SYNOPSIS 🫶

int t4vf_iq_free (struct adapter *adapter , unsigned int iqtype ,
       unsigned int iqid , unsigned int fl0id , unsigned int fl1id );

like, five things go in, one int comes out, no cap. ✨

---

💖 ARGUMENTS 💖

• adapter — the adapter, aka the whole vibe. this is the thing you're operating on, bestie.
• iqtype — the ingress queue type, like FW_IQ_TYPE_FL_INT_CAP, etc. yes, "etc." — the manpage said etc. and i'm not about to guess at numbers that aren't written down. 🙈
• iqid — the ingress queue ID. the main character ID, honestly. 👑
• fl0id — the FL0 queue ID, or 0xffff if there's no attached FL0. that 0xffff is the "nobody's home" signal, so don't get it twisted. 💀
• fl1id — the FL1 queue ID, or 0xffff if there's no attached FL1. same deal, same little 0xffff escape hatch. 🌈

---

🔥 DESCRIPTION 🔥

t4vf_iq_free frees an ingress queue and its associated free lists, if any. that's the whole plot. it's giving "spring cleaning but make it kernel." 🧚✨ and note the "if any" — the free lists are only a thing if they're actually attached, which is exactly why fl0id and fl1id have that 0xffff option. iykyk. 💅

💜 and that's the page!! this came from the source path ./drivers/net/ethernet/chelsio... (yes it's truncated exactly like that, don't @ me) and the date on it is October 2026. go free those queues, bestie. periodt. 🎀🌟
