hello,

rtl8169 is popular in cheap MB, so it is installed in my many MBs.
however, cat /dev/kmesg claims:
rtl8169: oui 0x732 phyno 1, macv = 0x3c000000 phyv = 0x0002
#l0: rtl8169: 100Mbps port 0xD000 irq 10: 001fd0169891

the “100Mbps" in the message is correct or not?

I also feel rtl8169 is slow, so I replace on-board rtl8169 by intel’s card  if possible.
