bnx2x_get_fw_mac_addr(9)

💖 bnx2x_get_fw_mac_addr 💖

okay so bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're fancy now. this page is all about bnx2x_get_fw_mac_addr, and honestly? it's the little sibling that undoes what the other one did. iconic behaviour, no cap.

---

✨ NAME ✨

bnx2x_get_fw_mac_addr — revert the bnx2x_set_fw_mac_addr().

like, literally the undo button. the "jk, put it back" of MAC address firmware stuff. 🎀

---

🌸 SYNOPSIS 🌸

void bnx2x_get_fw_mac_addr (__le16 *fw_hi , __le16 *fw_mid , __le16
*fw_lo , u8 *mac );

it returns void btw — so don't go looking for a return value, she gives you nothing back and that's her vibe 💅

---

🦋 ARGUMENTS 🦋

four little besties walk into a function:

• fw_hi — address. yes bestie, that's the whole description, we keep it real here ✨
• fw_mid — address. another one. she's in the middle, as the name suggests 🎀
• fw_lo — address. the low one. rounding out the trio 🫶
• mac — mac address. the actual star of the show, the main character, the reason we're all here 👑
