devlink: let driver opt out of automatic phys_port_name generation
[ 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.
