This patchset fixes a number of issues related to ibmvnic reset uncovered from testing new Power9 machines with Everglades adapters and the new functionality to change mtu and other parameters in the driver.
Changes since v1: -In patch 1/3, added the line to free the long term buffers before allocating a new one. This change inadvertently uncovered the problem that the number of queues can change after a failover as well. To fix this, we check whether or not the number of queues has changed in do_reset and if they have, we do a full release and init of the queues. -In patch 1/3, added variables to the adapter struct to track how many rx/tx pools have actually been allocated and modify the release pools routines to use these values rather than the possibly incorrect req_rx/tx_queues values.
