Testcase 909: ofproto-dpif - patch ports
The ofpbuf->base is set to OFPBUF_STUB at
ofputil_decode_switch_features()->ofpbuf_use_const()
so ofpbuf_delete does not free it. Call trace is below:
vconn_stream_recv(vconn-stream.c:155)
do_recv(vconn.c:640)
vconn_recv(vconn.c:598)
vconn_recv_block(vconn.c:738)
vconn_recv_xid__(vconn.c:758)
port_iterator_fetch_features(ovs-ofctl.c:846)
port_iterator_init(ovs-ofctl.c:889)
fetch_ofputil_phy_port(ovs-ofctl.c:975)
