[Minios-devel] [UNIKRAFT PATCH] lib/uknetdev: Zero-initialize netdev data

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

Whenever a network device is registered by a driver to the uknetdev
API, libuknetdev allocates an API-internal data structure that is used
to track the state of the device state. Subsequent API calls are
assuming that this allocation was zero-initialized. Otherwise,
assertions fail unexpectedly.
