Subject: [PATCH net-next 00/12] ionic memory usage rework

Previous review comments have suggested [1],[2] that this driver
needs to rework how queue resources are managed and reconfigured
so that we don't do a full driver reset and to better handle
potential allocation failures.  This patchset is intended to
address those comments.

The first few patches clean some general issues and
simplify some of the memory structures.  The last 4 patches
specifically address queue parameter changes without a full
ionic_stop()/ionic_open().
