tb_switch_d..._dp_resource(9)

💅 tb_switch_d..._dp_resource(9) 💅

okay bestie, we're in the Kernel API Manual, section 9, and this page is exactly this iconic little number: tb_switch_d..._dp_resource(9). no cap, the title ate and left crumbs. 🍓

🌸 NAME 🌸

tb_switch_dealloc_dp_resource — De-allocate DP resource. that's the whole name-section vibe. 💖

✨ SYNOPSIS ✨

void tb_switch_dealloc_dp_resource (struct tb_switch *sw , struct tb_port *in );

🎀 ARGUMENTS 🎀

• sw — the switch whose DP resource is being de-allocated. bestie, this is the one getting its DP resource cleaned up. 🫶
• in — the DP IN port. yes, literally the DP IN port. 💅

🦋 DESCRIPTION 🦋

okay so this function de-allocates a DP resource that was previously allocated for DP tunneling. that's the entire description, and honestly? it's giving “clean up your own mess” main character energy. ✨ no extra lore, no secret side quests — just the de-allocation. 🧚
