I know I can get NIC speed info from "MSNdis_LinkSpeed" but so far
have not found a WMI bucket for TX duplex (e.g., half/full) info.

Also, I've noticed WMI NIC linkspeed values of 200MBps (they're
usually 100MBps and 1000MBps in the network I'm monitoring). Could
200MBps perhaps indicate 100MBps Full Duplex?

TIA! Any help would be greatly appreciated.
