✨ arc_free_tx_queue(9) ✨

okay bestie, welcome to the Kernel API Manual page for arc_free_tx_queue — the function whose whole personality is "free skb from tx queue" 💅

🌸 NAME 🌸

arc_free_tx_queue — literally just frees skb from the tx queue, that's the whole gig, no cap 🎀

🦋 SYNOPSIS 🦋

void arc_free_tx_queue (struct net_device *ndev );

nothing extra, nothing sneaky — it takes one thing and gives you back void (as in: it returns nothing, not even a vibe check) 💖

💜 ARGUMENTS 💜

  • ndev — pointer to the network device 👑 that's it, that's the whole argument list, she's lowkey minimal and we respect it.

🌈 DESCRIPTION 🌈

so here's the tea ☕ — this function must be called while EMAC disable. like, that's not a suggestion, that's the whole rule fr fr 🙈. Read it, memorise it, live it.

⚠️ seriously, the manpage is very clear and very brief on this: the call has to happen while EMAC is disabled. Not before, not "eh it'll probably be fine" — disabled. periodt 💀

arc_free_tx_queue frees skb from the tx queue. That's the description, that's the source of truth, I'm not adding lore that isn't there 🫶
