Hi Team,

I am was trying to put log in the datapath module in Linux environment to
trace the flow if we ping one host to another host using ovs switch(using
mininet emulator)..

Inside *vport.c* file *ovs_vport_send *function is being called and then
internally it calls *vport->ops->send*() function I am unable to trace from
this function , can anyone tell me *where the call will go after calling
vport->ops->send* function  inside* vport.c* file.


Please give your valuable suggestions !

It will go to the vport driver's registered send function - you can get the name via the vport
structure's net_device member dev->name.
