💅 e1000_rar_set_pch_lpt — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual page for e1000_rar_set_pch_lpt(9) — yes that name is a mouthful, yes it's iconic, and yes we're gonna get through it together 🫶

✨ NAME ✨

e1000_rar_set_pch_lpt — set receive address registers. that's it, that's the whole vibe 💅

🦋 SYNOPSIS 🦋

int e1000_rar_set_pch_lpt (struct e1000_hw *hw , u8 *addr , u32 index );

like, literally just those three things and you're in 👑

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. the main character, the hardware handle itself 🌸
  • addr — pointer to the receive address. the address you're shoving into the register, bestie 🐝
  • index — receive address array register. which slot in the array we're touching, iykyk ✨

💖 DESCRIPTION 💖

so what does it actually do? it sets the receive address register array at index to the address passed in by addr. simple, clean, ate 💅

now here's the lore for LPT specifically, and this part is important so don't scroll past it 🙈:

  • RAR[0] is the base address register that is to contain the MAC address.
  • SHRA[0-10] are the shared receive address registers that are shared between the Host and manageability engine (ME).

that's the whole thing, no cap. the Host and the ME are literally sharing those registers, so bestie, be normal about it 🫶
