2022-11-11devlink: Fix warning when unregistering a portIdo Schimmel1-2/+2
When a devlink port is unregistered, its type is expected to be unset or otherwise a WARNING is generated [1]. This was supposed to be handled by cited commit by clearing the type upon 'NETDEV_PRE_UNINIT'. The assumption was that no other events can be generated for the netdev after this event, but this proved to be wrong. After the event is generated, netdev_wait_allrefs_any() will rebroadcast a 'NETDEV_UNREGISTER' until the netdev's reference count drops to 1. This causes devlink to set the port type back to Ethernet. Fix by only setting and clearing the port type upon 'NETDEV_POST_INIT' and 'NETDEV_PRE_UNINIT', respectively. For all other events, preserve the port type.

2022-11-10ethtool: ethtool_get_drvinfo: populate drvinfo fields even if callback exitsVincent Mailhol1-3/+10
If ethtool_ops::get_drvinfo() callback isn't set, ethtool_get_drvinfo() will fill the ethtool_drvinfo::name and ethtool_drvinfo::bus_info fields. However, if the driver provides the callback function, those two fields are not touched. This means that the driver has to fill these itself. Allow the driver to leave those two fields empty and populate them in such case. This way, the driver can rely on the default values for the name and the bus_info. If the driver provides values, do nothing.
