Information on non-self packets over the mesh

[praveen]

Hi,

mwifi_read()is used to 'Receive a packet targeted to self over the mesh network'
Is there anyway to know that a packet was received by the node which was no meant for self and but it was relayed through to reach the destination address?
This is basically to track the route of data packet from source to destination. Or is there any better ways to do this?

Thanks
