e1000_netpoll(9)

✨ e1000_netpoll — from the Kernel API Manual, section 9 ✨

okay so bestie 💖 we are looking at a tiny little page straight out of the Kernel API Manual, and it's literally just e1000_netpoll(9). It is short, it is iconic, and every single detail is right here. No cap. 🫶

🌸 NAME 🌸

literally just e1000_netpoll — the NAME line has nothing after the dash, so there's no glam little one-liner description here. That's not me skipping it, that's the whole vibe of the page. 💅

💅 SYNOPSIS 💅

void e1000_netpoll (struct net_device *netdev );

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure. yeah bestie, it's the NIC's whole personality in one struct. 🦋

🦋 DESCRIPTION 🦋

It's a polling 'interrupt' — yes the quotes around the word "interrupt" are doing a lot of heavy lifting, it's the polling version of an interrupt. Things like netconsole use it to send skbs without having to re-enable interrupts, which is lowkey the entire point of it. 🫶

Important little note bestie: it is not called while the interrupt routine is executing. So when the interrupt routine is running, this function is literally not invited to the function. Keep that energy. 💅

🫶 SEE ALSO 🫶

Kernel file ./drivers/net/ethernet/intel/e1000e/netdev.c — that's the home base. 🏠

🎀 cute little sign-off 🎀

This page is dated October 2026, and the footer shows the source as ./drivers/net/ethernet/intel/e... — same netdev.c bestie from up there, just cutely shortened. 💖 It's e1000_netpoll(9), Kernel API Manual, and that's the whole page. mwah 💋
