Hi i am using,
(Open vSwitch) 2.7.4
DB Schema 7.14.0
Openflow version 1.5
On deleting a flow i am encountering this error, this is a message sent in
response to the flow rule being removed.
However the flow deletion is going successfully, but Ryu is not able to
parse this message i believe.
Encountered an error while parsing OpenFlow packet from switch. This
implies the switch sent a malformed OpenFlow packet. version 0x06 msg_type
11 msg_len 72 xid 0 buf 0x06 0x0b 0x00 0x48 0x00 0x00 0x00 0x00 0x00 0x00

*assert value_len > 0*

it would be very helpful if you could look into this.
Thanks,
