mlx4: make sure to always set the port type
Even tho mlx4_core registers the devlink ports, it's mlx4_en and mlx4_ib which set their type. In situations where one of the two is not built yet the machine has ports of given type we see the devlink warning from devlink_port_type_warn() trigger. Having ports of a type not supported by the kernel may seem surprising, but it does occur in practice - when the unsupported port is not plugged in to a switch anyway users are more than happy not to see it (and potentially allocate any resources to it). Set the type in mlx4_core if type-specific driver is not built. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S.
