Bug ID: 1129 Summary: net/mlx5: cannot transmit if Tx queue is setup with maximum number of descriptors Product: DPDK Version: 22.11 Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: Normal Component: ethdev Assignee: dev@dpdk.org Reporter: andrew.rybche...@oktetlabs.ru Target Milestone: --- net/mlx5: cannot transmit if Tx queue is setup with maximum number of descriptors net/mlx5 does not report Rx/Tx descriptors limits (min/max/align). As the result application sees theoretical maximum UINT16_MAX (65535) which is set as the default by ethdev. If application tries to use the value to setup Tx queue, setup succeed, but Tx burst always returns 0. I guess the reason is in the following log message: mlx5_net: port 0 increased number of descriptors in Tx queue 0 to the next power of two (0) i.e. effective number of descriptors is equal to 0. -- You are receiving this mail because: You are the assignee for the bug.
