Support for ENA NETMAP partial initialization

Authored by on Oct 8 2019, 8:26 AM.



In NETMAP mode not all queues need to be allocated to NETMAP. Some of
them could be left to the kernel. Configuration is managed by the flags
nr_mode and nr_pending_mode provided per each NETMAP kring.

ENA driver checks those flags and perform proper rings initialization.
