[ovs-discuss] Link Control capabilities for DPDK ports

Hello community,

I need help in figuring out how if OpenvSwitch at the moment offers any capabilities to set the link speed and the duplex settings of a physical DPDK NIC.
For a non-DPDK port, there is ethtool however this only works for ports in the kernel space. The DPDK library offers a function to configure link speed but I’m wondering if it is already integrated into OVS’s source code and thus configurable through the OVS interface.

I saw on this website here<http://docs.openvswitch.org/en/latest/topics/dpdk/phy/> some information on Flow Control but nothing related to link speed.

I highly appreciate your help!
Thanks in advance.
