But, with software encryption mode, key is never plumbed to firmware. Due to this, a traffic failure in software encryption mode has been observed. Hence, firmware has introduced a flag to differentiate software encryption mode. This flag can be passed during vdev_start command. Enable WMI_VDEV_START_HW_ENCRYPTION_DISABLED flag in vdev_start command to notify firmware to disable hardware encryption for a vdev. This is set if raw mode software encryption is enabled.
