Even using `ifconfig eth0 mtu 1000` it doesn't work. My dpdk api shows 1500 mtu value.
And when I try to use l3fwd api and settings --enable-jumbo --max-pkt-len 9000 for example, it doesn't work. it appears: Cause rte_eth_tx_queue_setup: err-22, port=0 Any tips? I'm using Ubuntu 16.04 and VMXNET3. thanks On Mon, Aug 22, 2016 at 10:12 AM, Victor Detoni <victordetoni at gmail.com> wrote: > Stephen, thank you for your answer. > > When you say "stop the device, configure new settings, and start", you > mean use these functions rte_eth_dev_stop and rte_eth_dev_start? > > On Mon, Aug 22, 2016 at 2:27 AM, Stephen Hemminger < > stephen at networkplumber.org> wrote: > >> only some device drivers support changing MTU via the change API. >> For the rest the application has to stop the device, configure new >> settings, and start. >> > >
