netdev-dpdk: Add Flow Control support.
Add support for flow-control(mac control frame) to DPDK enabled physical
port types. By default, the flow-control is OFF on both rx and tx side.
The flow control can be enabled/disabled either when adding a port to OVS
or at run time.
For eg:
To enable flow control support at tx side while adding a port, add the
'tx-flow-ctrl' option to the 'ovs-vsctl add-port' command-line as below.
'ovs-vsctl add-port br0 dpdk0 -- \
set Interface dpdk0 type=dpdk options:tx-flow-ctrl=true'
Similarly to enable rx flow control,
'ovs-vsctl add-port br0 dpdk0 -- \
set Interface dpdk0 type=dpdk options:rx-flow-ctrl=true'
And to enable the flow control auto-negotiation,
'ovs-vsctl add-port br0 dpdk0 -- \
set Interface dpdk0 type=dpdk options:flow-ctrl-autoneg=true'
To turn ON the tx flow control at run time(After the port is being added
to OVS), the command-line input will be,
'ovs-vsctl set Interface dpdk0 options:tx-flow-ctrl=true'
The flow control parameters can be turned off by setting 'false' to the
respective parameter. To dsiable the flow control at tx side,
'ovs-vsctl set Interface dpdk0 options:tx-flow-ctrl=false'
