Net DIM API exposes the main function net_dim().
This function is the entry point to the Net
DIM algorithm and has to be called every time the driver would like to check if
it should change interrupt moderation parameters. The driver should provide two
data structures: struct dim and struct dim_sample. Struct dim
data structures: :c:type:`struct dim <dim>` and
:c:type:`struct dim_sample <dim_sample>`. :c:type:`struct dim <dim>`
describes the state of DIM for a specific object (RX queue, TX queue,
other queues, etc.). This includes the current selected profile, previous data
samples, the callback function provided by the driver and more.
Struct dim_sample describes a data sample, which will be compared to the
data sample stored in struct dim in order to decide on the algorithm's next

struct dim to the net_dim() function call. It is advised for each entity
