re0 at pci2 dev 0 function 0 "Realtek 8168" rev 0x11: RTL8168G/8111G (0x4c00), msi, address 9c:5c:8e:90:85:b6 re(4), especially the newer ones, are really not that bad. If you're referring to Bill Paul's comments in rl(4) rtl81x9.c that refers to a very old NIC that won't be seen on anything even vaguely recent. >>> > I have an OpenBSD 7.2 router that I have PPPoE passthrough configured to >>> > my >>> > ISP's Fibre modem on its 10G switch.
