I don't see RLT8125 parts listed in if_re(4) or if_re.c, and that appears to be the only driver for RealTek gigabit NICs? I don't know if that specific chipset is supported, but based on experience with re(4) 1 Gbps NICs, I would avoid it like the plague. I have several home "servers" with on board re(4) NICs (disabled in firmware now, so I can't get the specific chipset). I would have random connectivity problems such as samba shares randomly disappearing or systems becoming unresponsive over the network, especially during a file transfer (size didn't matter). While annoying, I never spent the time to get to the bottom of it. One day I actually paid some attention to /var/log/messages and saw frequent, random link state changes (DOWN then UP) across all of the machines. From some googling, this seems to be a common issue. Replaced them all with some Intel em(4) NICs and things have been solid since. Hope that helps. Chris
