Linux Network Question:
I have a new motherboard, which has two ethernet ports, one is the Realtek 8126 port, which is 5G, and the other is Realtek 8125 port, which is 2.5G.
The eth0 seems to be the 5G port, and eth1 is the 2.5G.
eth0 does not connect.
alexius@Chance:/etc/sysconfig/network> lspci | grep Ethernet
06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125 2.5GbE Controller (rev 05)
07:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8126 5GbE Controller (rev 01)
eth0 is unplugged at the moment, but if I run "ip a" it isn't even listed there.
...where do I go to tell it to actually see that one?
