Use typed queues for OF message processing
Process OF messages through 8 queues. Output queue for messages
controlled per OF Agent with help of message classifiers.
Queues can be configured through component configuration mechanism
for "org.onosproject.openflow.controller.impl.OpenFlowControllerImpl"
component.
Classifiers can be configured through NetworkConfig API in the following
form:
{
"devices": {
"of:0000000000000001": {
"classifiers": [{
"ethernet-type":"LLDP",
"target-queue":0
},{
"ethernet-type":"BDDP",
"target-queue":0
},{
"ethernet-type":"0x1234",
"target-queue":1
}]
}
}
}
Where "target_queue" is queue number from 0 to 7 (7 is default queue),
"ethernet_type" is a type of a packet either in "0xFFFF" from or enum
name as defined in the "org.onlab.packet.EthType.EtherType" enum.
