Bug ID: 43 Summary: "rte_eth_tx_queue_setup" will be failed to called if argument "tx_conf" not specified Product: DPDK Version: 18.05 Hardware: x86 OS: Linux Status: CONFIRMED Severity: normal Priority: Normal Component: ethdev Assignee: dev@dpdk.org Reporter: cnli...@gmail.com Target Milestone: --- OS: Ubuntu 16.04 x86_64 in virtualbox interfaces: 0000:00:08.0 '82540EM Gigabit Ethernet Controller 100e' drv=igb_uio unused=e1000,uio_pci_generic 0000:00:09.0 '82540EM Gigabit Ethernet Controller 100e' drv=igb_uio unused=e1000,uio_pci_generic When start "./build/app/ip_pipeline -l 0-3 -n 1 -- -s ./examples/l2fwd.cli", it will be failed to add link, and reports the error: eth_em_tx_queue_setup(): 0x5f6f6c0: Tx queue offloads 0x801d don't match port offloads 0x0 or supported port offloads 0xf or supported queue offloads 0xf Command "link" failed. The reason is at rte_ethdev.c line 1610, it will set full tx offloads in function "rte_eth_convert_txq_flags" if default_txconf.txq_flags is 0, which is wrong. One proper fix way is driver should set proper "ETH_TXQ_FLAGS_NOXXXX" flags to default_txconf.txq_flags. Any idea? -- You are receiving this mail because: You are the assignee for the bug.
