[ Upstream commit 8d5b0bf611ec5b7618d5b772dddc93b8afa78cb8 ]
We observed that packets and bytes count are not reset
when user performs interface down. Eventually, tx queue is
exhausted and packets will not be sent out.
To avoid this problem, resets tx queue in ndo_stop.
Fixes: 533dd11a12f6 ("net: socionext: Add Synquacer NetSec driver")
