[xubuntu-users] Wrong Network device ID

[Tim]

I have just done a fresh install of 14.04 on my PC and while the network 
connection has worked out of the box, I have just noticed that rather 
than eth0 as the device ID it has been given p2p1? How do I get Xubuntu 
to recognise my on board network card as eth0. There are no other 
network device installed, lspci returns

03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. 
RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)

Any suggestions
