i40e_get_mac_addr(9)

💅 i40e_get_mac_addr — Kernel API Manual ✨

okay so this one is short and sweet, bestie — it's a little kernel function that goes and fetches the adapter's MAC address for you. no cap, that's the whole vibe 🎀

🌸 NAME 🌸

i40e_get_mac_addr — get MAC address 💖

✨ SYNOPSIS ✨

int i40e_get_mac_addr (struct i40e_hw *hw , u8 *mac_addr );

🫶 ARGUMENTS 🫶

• hw — pointer to the HW structure 💻 like, hand over your hardware struct and we're good
• mac_addr — pointer to MAC address 🎀 this is where the address goes, so make sure it's pointing somewhere real, mwah

🔥 DESCRIPTION 🔥

Reads the adapter's MAC address from register 👑 that's it, that's the function. short queen energy, she does one thing and she does it slayfully 💅

👑 SEE ALSO 👑

the source lives here, in the kernel file ./drivers/net/ethernet/intel/i40e/i40e_common.c 🦋
