💅 nps_enet_set_rx_mode — the Kernel API Manual, bestie edition

okay so this is nps_enet_set_rx_mode, and it lives in section 9 of the Kernel API Manual (the kernel-functions one, iykyk). it's short, it's sweet, it's a little icon, and we're gonna get into it ✨

🌸 NAME 🌸

nps_enet_set_rx_mode — literally just: change the receive filtering mode. that's it. that's the whole job 🎀

---

✨ SYNOPSIS ✨

void nps_enet_set_rx_mode (struct net_device *ndev );

returns nothing (void, no notes, no drama), takes exactly one thing. slay 💅

---

🫶 ARGUMENTS 🫶

• ndev — pointer to the network device. that's the whole argument list, one (1) pointer, and it's the net device we're messing with 💖

---

🔥 DESCRIPTION 🔥

so what does it actually do?? it enables/disables promiscuous mode. that's the vibe. that's the function. flipping the receive filtering between "only stuff addressed to me" and "honestly, hand me everything" 🙈💀

ngl, if you're touching receive filtering on real hardware, know what you're doing — promiscuous mode is not a casual accessory 🫶
