Driver version upgrade is connected with support for the new device
fetures, like Tx drops reporting or disabling meta caching.
Moreover, the driver configuration from the sysctl was reworked to
provide safer and better flow for configuring:
* number of IO queues (new feature),
* drbr size on Tx,
* Rx queue size.
Moreover, a lot of minor bug fixes and improvements were added.

As functions which are declared in the header files are intended to be
the interface and are going to be used by other files, it's better to
include argument names in the definition, so the caller won't have to
check the .c file in order to check their meaning and order.

Move Rx/Tx routines to separate file.
Some functions:
* ena_restore_device,
* ena_destroy_device,
* ena_up,
* ena_down,
* ena_refill_rx_bufs
could be reused in upcoming netmap code in the driver. To make it
possible, they were moved to ena.h header.
