Bug ID: 1719
Summary: mlx5 PMD returns incorrect max_mtu and max_rx_pktlen
from rte_eth_dev_info_get()
Product: DPDK
Version: 24.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: dsosnowski@nvidia.com
Target Milestone: ---
mlx5 PMD returns incorrect values for max_mtu and max_rx_pktlen from
rte_eth_dev_info_get(). To be specific:
- max_mtu is set to UINT16_MAX - set statically in rte_eth_dev_info_get()
implementation as a fallback; it is never updated based on device's
capabilities in mlx5 PMD implementation
- max_rx_pktlen is set to 65536 - incorrect value; should be read based on
device's capabilities
