Don't know if it's any help, but here's what ifconfig shows on my 6.2 desktop, which has a similar ethernet interface (RTL8168C/8111C) and static IP:
Code:
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
lladdr xx:xx:xx:xx:xx:xx
index 1 priority 0 llprio 3
groups: egress
media: Ethernet autoselect (100baseTX full-duplex,rxpause,txpause)
status: active
inet 192.168.x.x netmask 0xffffff00 broadcast 192.168.x.255
