Runinng l2fwd DPDK Example on my machine makes me loose the interface

Hi All,

I am new to intel DPDK and trying out some examples.

Below is the list of interfaces that i have.

after i run l2fwd example,I loose eth0,eth1,eth2,eth3 interface as a result of which i loose the connectivity to the box.

Ifconfig doesn't show eth0,eth1,eth2,eth4 all being Intel NIC's.

Please let me know how to run the examples on specific interface and if i am missing something.

Please find the interface and other information below.

Let me know if you need any more info.

Thanks

Thilak Raj S
