Thanks Ben,


*OVS doesn't do anything special with it.  It treats it like any
otherfield.*

Could you please elaborate the above mentioned point.

My intention here was to know how OVS  Queue the traffic(*Packets*) at port
which are coming from datapath(kernel space), it would really help me if
you point out the file name in OVS which handles the Queue mechanism .



*Regards*
Rakesh Kumar.
