KyLinV10 安装realtek-r8125 2.5G网卡驱动。

去github https://github.com/awesometic/realtek-r8125-dkms/releases
然后

This is the Linux device driver released for RealTek RTL8125 2.5Gigabit Ethernet controllers with PCI-Express interface.

- Kernel source tree (supported Linux kernel 2.6.x and 2.4.x)
- For linux kernel 2.4.x, this driver supports 2.4.20 and latter.
- Compiler/binutils for kernel compilation

Unpack the tarball : # tar vjxf r8125-9.aaa.bb.tar.bz2

Change to the directory:
	# cd r8125-9.aaa.bb

If you are running the target kernel, then you should be able to do :

	# ./autorun.sh	(as root or with sudo)

You can check whether the driver is loaded by using following commands.

	# lsmod | grep r8125
	# ifconfig -a

Transmitting Jumbo Frames, whose packet size is bigger than 1500 bytes, please change mtu by the following command.

# ifconfig ethX mtu MTU

, where X=0,1,2,..., and MTU is configured by user.

RTL8125 supports Jumbo Frame size up to 9 kBytes.

Get/Set device EEE status

	Get EEE device status （查看你的网卡，enp1s0根据你实际的来 通过 ifconfig 查看，比如我的是p1p1）
	# ethtool --show-eee enp1s0

	Set EEE device status *（强行设置链接速率）
	# ethtool --set-eee enp1s0 eee on tx-lpi on tx-timer 1546 advertise 0x0008 (100M full)
	# ethtool --set-eee enp1s0 eee on tx-lpi on tx-timer 1546 advertise 0x0020 (1G)
	# ethtool --set-eee enp1s0 eee on tx-lpi on tx-timer 1546 advertise 0x8000 (2.5G)
