Re: [PATCH v2 net-next] net: core: devlink: add 'dropped' stats field for DROP trap action

Whenever query statistics is issued for trap with DROP action,
devlink subsystem would also fill-in statistics 'dropped' field.
In case if device driver did't register callback for hard drop
statistics querying, 'dropped' field will be omitted and not filled.
Add trap_drop_counter_get callback implementation to the netdevsim.
Add new test cases for netdevsim, to test both the callback
functionality, as well as drop statistics alteration check.

Please stick to RFC since there is no upstream user for this (if you
need to repost).
