tb_switch_tmu_is_enabled(9)

💖 tb_switch_tmu_is_enabled(9) 💖

okay bestie, welcome to the Kernel API Manual page for tb_switch_tmu_is_enabled(9) — manual name folded in right here because we're efficient like that 💅. This is the little helper that checks whether a router's TMU mode is enabled. No cap.

✨ NAME ✨

tb_switch_tmu_is_enabled — checks if the specified TMU mode is enabled. 🫶

🌸 SYNOPSIS 🌸

bool tb_switch_tmu_is_enabled (const struct tb_switch *sw );

That signature is exactly the one, spacing and all — keep it cute and precise. 😌

🎀 ARGUMENTS 🎀

• sw — the router whose TMU mode you want to check, typed as const struct tb_switch *. It's giving "tell me about this switch" energy.

🦋 RETURN 🦋

This returns true when the hardware TMU configuration matches the requested configuration (and it is not TB_SWITCH_TMU_MODE_OFF). Otherwise it returns false, periodt. 💅
