re(4) MAC address


I was testing a NH-230/231 NAS (running sandpoint) and wondered why
the PPCBoot firmware and the previously installed Linux used a different
MAC address than NetBSD does.

I found out that NetBSD's re(4) driver is reading the MAC from EEPROM
while PPCBoot and Linux are reading it from the chip's ID-registers

What is correct? This is a Realtek 8169S:

# pcictl pci0 dump -d 15
PCI configuration registers:
  Common header:
    0x00: 0x816910ec 0x02b00107 0x02000010 0x00008008

    Vendor Name: Realtek Semiconductor (0x10ec)
    Device Name: 8169/8110 10/100/1000 Ethernet (0x8169)

Sorry for cross-posting, but I couldn't decide whether this belongs to
tech-kern or tech-net.
