ei_rx_overrun(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ei_rx_overrun(9) 💖

okay so bestie, welcome to the ei_rx_overrun(9) page from the Kernel API Manual — yes that's the whole manual name, we're not copying the line, we're just mentioning it, slay ✨

🌸 NAME 🌸

ei_rx_overrun — handle receiver overrun 🫶

✨ SYNOPSIS ✨

void ei_rx_overrun (struct net_device *dev );

🎀 ARGUMENTS 🎀

  • dev — the network device that threw the exception 😭 like, it's the one going through it, be nice to it

💅 DESCRIPTION 💅

So picture this: we have a receiver overrun 💀 and we've gotta kick the 8390 to get it started again. Sounds easy? It is not. The problem — and I cannot stress this enough — is that you have to kick it exactly as NS prescribes in the updated datasheets, or, and I quote, "the NIC may act in an unpredictable manner." 🙈

And it gets worse, because that includes causing "the NIC to defer indefinitely when it is stopped on a busy network." Ugh. Literally ugh. 😭

⚠️ Called with the lock held. Do not call this with interrupts off or your computer will hate you — it takes 10ms or so. Not kidding, 10ms is an eternity in kernel time, bestie. 🔥

🌈 SEE ALSO 🌈

Kernel file ./drivers/net/ethernet/8390/lib8390.c — plus these icons, go read them too 👑

and that's the whole vibe, bestie — this page lives in ./drivers/net/ethernet/8390 and it's stamped October 2026, so go forth and kick that 8390 exactly how NS says to 💜🦋 periodt
