Devlink fmsg is a mechanism to pass descriptors between drivers and devlink, in json-like format. The API allows the driver to add nested attributes such as object, object pair and value array, in addition to attributes such as name and value. Driver can use this API to fill the fmsg context in a format which will be translated by the devlink to the netlink message later. There is no memory allocation in advance (other than the initial list head), and it dynamically allocates messages descriptors and add them to the list on the fly. When it needs to send the data using SKBs to the netlink layer, it fragments the data between different SKBs. In order to do this fragmentation, it uses virtual nests attributes, to avoid actual nesting use which cannot be divided between different SKBs.
