__get_duplex(9)

💅 __get_duplex(9) — Kernel API Manual 💅

hey bestie 🌸 welcome to the Kernel API Manual page for __get_duplex(9). this is the bonding/3ad helper that tells you a port's duplex, and we're gonna read it together, no cap.

✨ NAME ✨

__get_duplex — get a port's duplex 💖

🎀 SYNOPSIS 🎀

u8 __get_duplex (struct port *port );

🦋 ARGUMENTS 🦋

• port — the port we're looking at 👀

💜 DESCRIPTION 💜

okay so this function returns port's duplex in 802.3ad bitmask format. i.e.: 0x01 if in full duplex, 0x00 otherwise. that's the whole vibe — literally the bitmask truth, no extra lore. ✨
