I use Debian sid and some weeks ago, a upgrade in some package caused a strange thing.
I use my computer, when my wired connection down. Sometimes only the IPv4, sometimes all the connections.
The symbol of the wired connection says that the connection is working. When i disable to use a wireless connection in the same network, it works.
When i use dmesg | grep r8169
r8169 Gigabit Ethernet driver 2.3LK-NAPI loaded
r8169 0000:02:00.0 eth0: RTL8168evl/8111evl at 0x (ptrval), ..., XID ... IRQ ..

dmesg | grep enp2s0
TCP: enp2s0: Driver has suspect GRO implementation, TCP performance may be compromised.
What is happening to my computer?
