From: David Arinzon <darinzon@amazon.com>

Queue stats using ifconfig and ip are retrieved
via ena_get_stats64(). This function currently does not take
the xdp sent or dropped packets stats into account.

This commit adds the following xdp stats to ena_get_stats64():
tx bytes sent
tx packets sent
rx dropped packets
