Post-v2.13.0
---------------------
- ovs-vswitchd no longer deletes datapath flows on exit by default.
- OpenFlow:
* The OpenFlow ofp_desc/serial_num may now be configured by setting the
value of other-config:dp-sn in the Bridge table.
v2.13.0 - xx xxx xxxx

Human readable description of datapath. It is a maximum 256
byte-long free-form string to describe the datapath for
debugging purposes, e.g. <code>switch3 in room 3120</code>.
The value is returned by the switch as a part of reply to OFPMP_DESC
request (ofp_desc). The OpenFlow specification (e.g. 1.3.5) describes
the ofp_desc structure to contaion "NULL terminated ASCII strings".
For the compatibility reasons no more than 255 ASCII characters should be used.
