When i run ifconfig eth0 see following lines:
eth0 Link encap:Ethernet HWaddr 08:00:27:42:81:a7
inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0

How can i reset these counters especially RX/TX packets?
Those counters are kept by the kernel, so your answer depends on how your network card driver is built. Two possible choices:
If it is second, you can not reset counters without restarting the operating system. If it is first, you can do it by unloading the module from the kernel and then loading it back again. If your NIC card use e1000 module, use following commands:
$ ifconfig eth0 down
$ modprobe -r e1000
$ modprobe e1000
$ ifconfig eth0 up
Use ethtool to find out your NIC module:
$ ethtool -i eth0
In front of driver you see your module name:
driver: e1000
version: 7.3.21-k8-NAPI
firmware-version:
...
Use apt-get to install ethtool as follow:
$ apt-get install ethtool
