✨ Constants ✨

these four are all masks, and they all live to do one job: fish a specific value out of the field. obsessed. 💅

• NVME_CTRL_RPMBS_NR_UNITS — a mask that gets you the value of the Number of RPMB Units. 🔢
• NVME_CTRL_RPMBS_AUTH_METHOD — a mask that gets you the value of the Authentication Method. 🔐
• NVME_CTRL_RPMBS_TOTAL_SIZE — a mask that gets you the value of Total Size. 📏
• NVME_CTRL_RPMBS_ACCESS_SIZE — a mask that gets you the value of Access Size. 🎯

reminder bestie: these are masks. you AND them with the field, you don't just read them raw. mask behavior is the whole point, periodt. 💀
