Solve the problem that Qualcomm Atheros AR8161 Gigabit Ethernet NIC fails in Linux.

The NIC Of My Dell I2330R-168 integrated computer broke down after upgrading a kernel version.

ifconfig eth0eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 8192        inet 192.168.99.236  netmask 255.255.255.0  broadcast 192.168.99.255        inet6 fe80::221:70ff:fe6a:bd9c  prefixlen 64  scopeid 0x20<link>        ether 00:21:70:6a:bd:9c  txqueuelen 1000  (Ethernet)        RX packets 36202  bytes 49450919 (47.1 MiB)        RX errors 173  dropped 0  overruns 173  frame 0        TX packets 20661  bytes 1889686 (1.8 MiB)        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0        device interrupt 17 

 

Now the arch linux is installed, and the kernel is updated to the latest version.

uname -a4.4.1-2-ARCH #1 SMP PREEMPT Wed Feb 3 13:12:33 UTC

However, this problem still exists.

 

I suddenly thought that I should go to the kernel site to find the answer, so I searched for the NIC Driver name alx.

Https://bugzilla.kernel.org/buglist.cgi? Quicksearch = alx

Many people have encountered the same problem.

Https://bugzilla.kernel.org/show_bug.cgi? Id = 70761

You can solve this problem by changing mtu to 8192.

ifconfig eth0 mtu 8192

Someone has written a patch to solve this problem, but has not yet entered the kernel.

 

Since I am using arch linux, I will not compile the kernel myself in archlinux, so I will first set mtu to solve this problem.
