[PATCH net-next 07/13] liquidio: chip reset changes

From: Raghu Vatsavayi <hidden>
Date: 2016-06-22 05:55:23
Subsystem: cavium liquidio network driver, networking drivers, the rest · Maintainers: Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

This patch resolves the order of chip reset while destroying
the resources by postoponing soft reset in destroy resources
function until all queues are removed properly.
