devlink: let driver opt out of automatic phys_port_name generation

2025-08-28T14:34:42+00:00

[ Upstream commit c5ec7f49b480db0dfc83f395755b1c2a7c979920 ] Currently when adding devlink port, phys_port_name is automatically generated within devlink port initialization flow. As a result adding devlink port support to driver may result in forced changes of interface names, which breaks already existing network configs. This is an expected behavior but in some scenarios it would not be preferable to provide such limitation for legacy driver not being able to keep 'pre-devlink' interface name. Add flag no_phys_port_name to devlink_port_attrs struct which indicates if devlink should not alter name of interface.

devlink: avoid param type value translations

2025-05-07T01:21:11+00:00

Assign DEVLINK_PARAM_TYPE_* enum values to DEVLINK_VAR_ATTR_TYPE_* to ensure the same values are used internally and in UAPI. Benefit from that by removing the value translations.

devlink: Improve the port attributes description

2025-01-03T01:10:57+00:00

Current PF number description is vague, sometimes interpreted as some PF index. VF number in the PCI specification starts at 1; however in kernel, it starts at 0 for representor model. Improve the description of devlink port attributes PF, VF and SF numbers with these details.

devlink: Constify the 'table_ops' parameter of devl_dpipe_table_register()

2024-06-05T09:24:57+00:00

"struct devlink_dpipe_table_ops" only contains some function pointers. Update "struct devlink_dpipe_table" and the 'table_ops' parameter of devl_dpipe_table_register() so that structures in drivers can be constified. Constifying these structures will move some data to a read-only section, so increase overall security.
