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. =46rom some googling, this seems to be = a common issue. Replaced them all with some Intel em(4) NICs and things = have been solid since. =20 Hope that helps. Chris=
