raw/ioat: add device reset to configuration script
Currently once a device is configured, the user does not have the ability to reset the device via the script. This patch adds a device reset option to the script. For example "$dpdk_idxd_cfg.py 0 --reset" would reset device 0. Signed-off-by: Kevin Laatz <kevin.laatz@intel.com> Acked-by: Bruce Richardson <bruce.richardson@intel.com>
