XenServer 5.6 FP1 Realtek NIC Issue

If you are using Realtek NIC (RTL8111/8168B) and after upgraded from XS 5.6 to XS 5.6 FP1, you encountered the network is not working, try the following workaround.

$ echo "options r8169 use_dac=1" >> /etc/modprobe.conf

Restart and now the NIC should be functioning properly.
