I did some research and came to the following results: * For a non-DPDK port, there is ethtool however this only works for ports in the kernel space. I saw that there is a DPDK Kernel NIC Interface (KNI) that allows the use of the ethtool for DPDK ports however it says that it currently only provides minimal ethtool functionality such as querying but not changing link settin= gs. * I also discovered that the testpmd application offers a runtime function = to set the speed and duplex mode for a DPDK port but if I understood it correc= tly this app is designed to test DPDK and not to manage port settings. So I'm n= ot sure if I can use it to change the link speed / duplex in a persistent way. Is anyone aware of a way to manage the DPDK port speed and duplex systemwid= e? Does it perhaps work with any of the aforementioned applications and I just overlooked something? I would be very pleased about any ideas! Thanks in advance.
