rte_eth_dev_configure() failure with Tx offloads(0x200000) capability with dpdk-22.11.3 #4

Open Kwangbaek opened 11 months ago

Hi,

I’m trying to make an application which sends a packet traffic at line rate(100Gbps) making use of “Packet Pacing(tx_pp)” and "Real Time Scheduling" feature. However, I met an error message while enabling RTE_ETH_TX_OFFLOAD_SEND_ON_TIMESTAMP ‘rte_eth_dev_configure()’.

I don't have a Grandmaster and no ethernet switch at the moment, however, I really need this feature.

Please let me know if there is a way of running a generator in 5t5g repo(https://github.com/NVIDIA/5t5g) without synchronizing to a grandmaster. Or advise me on how to achieve it with some additional equipment.

Here is my configuration. a. Server/OS : a Dell Server with Red Hat Linux 8.8 b. CPU : Mellanox ConnectX-6 Dx Dual Port 100 GbE QSFP56 Network Adapter c. NIC card : ConnectX-6 DX d. NIC firmware : MLNX_OFED_LINUX-23.07-0.5.1.2-rhel8.8-x86_64.iso e. port configuration : loopback (port 0 tx -> port 1 rx, port 1 tx -> port 0 rx)

Kind regards,

Kevin

Is the generator supposed to work with DPDK version 22.11.3 ? I met a couple of compile error initially and then the failure in rte_eth_dev_configure() started to happen.
