I'm on linux mint.

I've just installed a PCIe gigabit network card (from eBay!) into my linux machine. I've already had to follow this guy's instructions to get the onboard NIC working correctly.

I don't know how to instruct linux to detect the new card. It's got an RTL8111C chip, so I assume it'll use the same driver as the onboard NIC.

When I plug a cable into the card, I can see a light on the switch, so I'm assuming it's okay.

here's dmesg output:

lapin@server /etc/network $ dmesg | grep "eth\|Ethernet"
[    2.618914] r8168 Gigabit Ethernet driver 8.037.00-NAPI loaded
[    2.619848] eth%d: 0xffffc90000656000, f4:6d:04:90:99:f0, IRQ 46

[   29.153143] r8168: eth0: link up
[   29.153508] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

and here's lspci:

lapin@server /etc/network $ lspci | grep Ethernet
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 06)

The motherboard is this one: http://www.asus.com/Motherboards/E35M1I_DELUXE/

whose specs say that the internal card is the "RealtekĀ® 8111E PCIe Gigabit LAN controller."

How can I get linux (mint) to recognize the newly installed card?

Are you sure it's plugged in? There is only one Ethernet device there. –  Michael Hampton Feb 16 at 22:27
    
The card is installed to the motherboard. When I hook up a cable, I'm getting a green light on the switch. –  user205935 Feb 16 at 22:29
    
So does that output in your question refer to the new NIC, or the onboard NIC? –  Michael Hampton Feb 16 at 22:32
    
The onboard chip is the 8111E, the PCIe NIC chip is 8111C. So it's impossible to tell. –  user205935 Feb 16 at 22:33

lspci should list the card regardless of whether or not the driver is installed. You may want to comb through all of lspci output, and watch out for unknown entries. Also, I suggest going through the motherboard manual to ensure you don't use a PCI-X slot adjacent to your video card, for example. Some motherboards don't like that, and in that case, the network card looks like it's working, but the BIOS never recognizes it, so the kernel of any OS doesn't see it. –  Rouben Feb 16 at 23:30
