Hi,
Please refer to the 'data' attribute of OFPPacketOut.
You can set a binary type value, which you want send, into this attribute.
e.g.)
req = ofp_parser.OFPPacketOut(datapath, buffer_id,in_port, actions,
data=<BINARY_TYPE_VALUE>)
FYI: For building a binary type packet data, Ryu provides the packet libraries.
'bin_packet' in the following example is a binary type value to send.

Thanks,
Iwase
