💅 mbx_ctrl_rd32 — a kernel API manual, but make it make sense

okay so bestie, welcome to the mbx_ctrl_rd32(9) page, from the Kernel API Manual ✨ this is the glow-up of a manual page, and honestly it's giving "small function, big main character energy" 🎀

✨ NAME ✨

mbx_ctrl_rd32 — reads a reg with base mbx->fwpf_ctrl_base 🫶

like literally that's the whole vibe. it reads a register, and the base it works off of is mbx->fwpf_ctrl_base. no cap.

🌸 SYNOPSIS 🌸

u32 mbx_ctrl_rd32 (struct mucse_mbx_info *mbx , u32 reg );

that's it, that's the whole signature 💖 u32 in, u32 out, immaculate.

🦋 ARGUMENTS 🦋

• mbx — pointer to the MBX structure 👑 this is your main character right here.

signed off from ./drivers/net/ethernet/mucse/r... 🍓 dated October 2026 💖 and yeah, the source string is literally truncated like that in the original — ./drivers/net/ethernet/mucse/r... — so we keep it exactly, bestie, we do not "fix" the vibes 😭 anyway slay, go read those registers responsibly ✨👑
