[ovs-dev] ovs-tcpdump error

[Bodireddy, Bhanuprakash]

Hi,

ovs-tcpdump throws the below error when trying to capture packets on one of the vhostuserports.

$ ovs-tcpdump -i dpdkvhostuser0
   ERROR: Please create an interface called `midpdkvhostuser0`
    See your OS guide for how to do this.
    Ex: ip link add midpdkvhostuser0 type veth peer name midpdkvhostuser02

$ ip link add midpdkvhostuser0 type veth peer name midpdkvhostuser02
     Error: argument "midpdkvhostuser0" is wrong: "name" too long

To get around this issue, I have to pass  '-mirror-to' option as below.

$ ovs-tcpdump -i dpdkvhostuser0 -XX --mirror-to vh0

Is this due to the length of the port name?  Would be nice to fix this issue.
