t4_eth_eq_free(9)

💖 t4_eth_eq_free(9) — Kernel API Manual 💖

okay bestie, listen up, because today we're looking at t4_eth_eq_free from the Kernel API Manual, and honestly? She's a short one but she matters. ✨

🌸 NAME 🌸

t4_eth_eq_free — free an Ethernet egress queue

yeah, that's it. that's the whole name. no notes. 💅

---

🦋 SYNOPSIS 🦋

int t4_eth_eq_free (struct adapter *adap , unsigned int mbox , unsigned
int pf , unsigned int vf , unsigned int eqid );

she takes five things and returns an int. main character energy from the very first line, fr fr. 👑

---

🎀 ARGUMENTS 🎀

• adap — the adapter. like, the whole NIC. the big one. the moment. 🫶
• mbox — the mailbox to use for the FW command. it's giving "post office but make it firmware" 📬
• pf — the PF owning the queue. (PF = Physical Function, iykyk) 💜
• vf — the VF owning the queue. (VF = Virtual Function, and yes they're a whole vibe) 🌈
• eqid — the egress queue id. the actual queue in question. the queen herself. 👑

---

⭐ DESCRIPTION ⭐

Frees an Ethernet egress queue.

that's the whole description. not me expecting more and getting one (1) sentence 😭. but honestly? iconic. she says exactly what she does and then leaves. no filler, no fluff, no "in conclusion". periodt. 💀

the way this function is highkey just "goodbye queue, you're free now" and dips. respect. 🫡

💀 SEE ALSO 💀

first up, the kernel file where this whole situation lives, bestie:

• Kernel file ./drivers/net/ethernet/chelsio/cxgb4/t4_hw.c

and now. the list. the list. she is LONG. she is thorough. she ate and left absolutely no crumbs, and we are gonna get through every single one of these together. hydrate first. 🍓

see? all of them. every single one. no crumbs, like I said. 🔥

heads up bestie: that eqid is an egress queue id, so if you're freeing a control queue or an offload queue, wrong function — check t4_ctrl_eq_free(9) or t4_ofld_eq_free(9) above. this one is Ethernet-specific only. 🧚

and that's the whole page, babe — short and slay. this cutie came out of ./drivers/net/ethernet/chelsio... in October 2026, page number t4_eth_eq_free(9), and now you know her. go free some queues responsibly. ily, bye! 💖🌸✨
