✨ NAME ✨

I40E_SET_PF_SD_ENTRY — marks the sd entry as valid in the hardware 👑

like, that's literally the whole job. it flips the little "yes this one counts" switch on an sd entry in the hardware. no cap 💅

🌸 SYNOPSIS 🌸

I40E_SET_PF_SD_ENTRY (hw , pa , sd_index , type );

that's the whole call, she's compact 🎀

💖 ARGUMENTS 💖

• hw — pointer to our hw struct 🫶 the hardware context, she's holding everything together.
• pa — pointer to physical address ✨ yes, physical, and yes it matters.
• sd_index — segment descriptor index 🌈 which sd entry we're marking, iykyk.
• type — if sd entry is direct or paged 🦋 so basically the flavor of that sd entry.
