Hi Tanvir, Then, we're talking about Linux specific sk_buf.mark, not a packet marking in general. In ryu library, you can find NXM_NX_PKT_MARK in ryu/ofproto/nicira_ext.py, and it should not be hard to use. https://github.com/osrg/ryu/blob/master/ryu/ofproto/nicira_ext.py#L385
BTW, set_field action to metadata field can be used to mark a packet as far as the packet is traveling in openflow pipeline.
