π e1000_read_mac_addr_generic(9)
okay so bestie, welcome to the Kernel API Manual page for e1000_read_mac_addr_generic(9) β yes the (9) means kernel section, that's just her main character era β¨ grab a snack, this one's short and sweet π
πΈ NAME
e1000_read_mac_addr_generic β Read device MAC address π
β¨ SYNOPSIS
s32 e1000_read_mac_addr_generic (struct e1000_hw *hw );
π¦ ARGUMENTS
hwβ pointer to the HW structure π«Ά literally just a pointer to the hardware struct, that's the whole vibe
π₯ DESCRIPTION
so what she does is reads the device MAC address from the EEPROM and stores the value πΎ that's it, that's the job, and she does it flawlessly, periodt.
and here's the little detail that's highkey iconic π: since devices with two ports use the the same EEPROM, we increment the last bit in the MAC address for the second port β so the two ports don't end up matching like twins who showed up in the same outfit ππ no cap, that's the whole trick.

ngl this page is small but she ate π no bugs noted here, just vibes and a correctly-read MAC address π
and that's the whole page bestie!! source/version is ./drivers/net/ethernet/intel/e... and she's dated October 2026 β ugh, timeless π°οΈβ¨ bye, ily, go read your EEPROM π§π
