Hello Team,

I want to set miss_send_length in the configuration reply. But I am unable
to set it. Can you please verify below procedure.

 I am sending OFPT_SET_CONFIG using RYU req =
ofproto_v1_3_parser.OFPSetConfig(datapath, ofproto_v1_3.OFPC_FRAG_MASK,
65533)

After sending it, verify using ovs-vsctl –O Openflow13 show br0

Sending  again OFPT_SET_CONFIG using RYU req =
ofproto_v1_3_parser.OFPSetConfig(datapath, ofproto_v1_3.OFPC_FRAG_DROP,

After sending it, verify using ovs-vsctl –O Openflow13 show br0

OFPT_GET_CONFIG_REPLY (OF1.3) (xid=0x5): frags=drop miss_send_len=0


Can you please suggest me how to configure it.

Neeraj
