✨ DESCRIPTION 👑

So what does this bad girl actually do? She initializes the passthru command buffer for the Set Features command with FID value NVME_FEAT_FID_EMB_MGMT_CTRL_ADDR 🧚

That's it, that's the whole job — but she does it flawlessly, periodt 🌈

lowkey important: data is a 512 byte buffer, so don't be out here handing her a tiny little snack-sized buffer 😭 she needs the full 512 bytes fr fr

okay that's the whole page bestie, go forth and set those features 💜
