    Hannes Reinecke authored
    Implement NVMe-oF In-Band authentication according to NVMe TPAR 8006.
    This patch adds two new fabric options 'dhchap_secret' to specify the
    pre-shared key (in ASCII respresentation according to NVMe 2.0 section
    8.13.5.8 'Secret representation') and 'dhchap_ctrl_secret' to specify
    the pre-shared controller key for bi-directional authentication of both
    the host and the controller.
    Re-authentication can be triggered by writing the PSK into the new
    controller sysfs attribute 'dhchap_secret' or 'dhchap_ctrl_secret'.
