RTL8111/8168B NIC & FreeBSD

we are trying to install FreeBSD on a computer that uses the NIC mentioned
above. The NIC is running under linux without problems, which we've tested
for several days transferring several GB of data.

The NIC is neither detected by the FreeBSD installer when attempting to
setup the network, nor after the system installation when booting from HD.
We've tested FreeBSD 8.x, 9.x and 10.x; same issues with this NIC.

We cannot use a different NIC (this one is onboard. The micro ATX mainboard
has no room left for any other device)

pciconf -l -v:

    vendor     = 'Realtek Semiconductor Co., Ltd.'
    device     = 'RTL8111/8168B PCI Express Gigabit Ethernet controller'
    class      = network
    subclass   = ethernet

    inet netmask 0xff000000

Even though "dmesg" shows the device "re0", it remains unknown to

"if_re" is already in the generic kernel, so it can't be loaded via
"kldload" as a module, right?

We've already addressed this problem here:
