>Description:
ASUS P5B motherboard with "RealTek PCI-E Gigabit LAN controller".
The device is identified by if_re driver, device re0 created, but it doesn't work.
Reports "no link" when in fact there is active DHCP connection.  

There is also RT8139 PCI NIC installed, but if_rl driver works fine for this NIC.

The problem only exists in FreeBSD. Under Solaris/Linux/Windows/DragonflyBSD both devices work fine at the same time.
>How-To-Repeat:
Perhaps use ASUS P5B motherboard and try a FreeBSD-based system; in Debian kFreeBSD the problem exists as well.
>Fix:
Couldn't fix this driver, used a downloaded driver called "rtl_bsd_drv_v179", which seems to be a modified version of the original, modified by RealTek according to the info in the source file.
