I think the idea would be to split the xmit/rcv pairs out onto a socket passively, where you attach a monitor. I'm not sure how that works for bringing the PHY link up from the perspective of the monitoring device, but that paper sent earlier discussed some strategies to fool the link into coming up.

> There is an official GigE cross over wiring, so that technique could probably be applied to GigE too. I can't remember where exactly I got the wiring for it, however I converted an RJ45 inline adaptor (i.e., female/female) to use it, and had no trouble bringing up 10, 100 and 1000 speeds across it, without any changes to the settings of the NIC interfaces.

I thought the idea was to tap/mirror the traffic of an *existing* (in
use) Ethernet connection? In that case, GigE crossover won't help you...
