      s390/ap/zcrypt: notify userspace with online, config and mode info · df6f508c
      Harald Freudenberger authored
      This patch brings 3 reworked/new uevent changes:
      * All AP uevents caused by an ap card or queue device now carry an
        additional uevent env value MODE=<accel|cca|ep11>. Here is an
        example:
          KERNEL[1267.301292] add	 /devices/ap/card0a (ap)
          ACTION=add
          DEVPATH=/devices/ap/card0a
          SUBSYSTEM=ap
          DEVTYPE=ap_card
          DEV_TYPE=000D
          MODALIAS=ap:t0D
          MODE=ep11			 <- this is new
          SEQNUM=1095
        This is true for bind, unbind, add, remove, and change uevents
        related to ap card or ap queue devices.
      * On a change of the soft online attribute on a zcrypt queue or card
        device a new CHANGE uevent is sent with an env value ONLINE=<0|1>.
        Example uevent:
          KERNEL[613.067531] change	/devices/ap/card09/09.0011 (ap)
          ACTION=change
          DEVPATH=/devices/ap/card09/09.0011
          SUBSYSTEM=ap
          ONLINE=0			<- this is new
          DEVTYPE=ap_queue
          DRIVER=cex4queue
          MODE=cca
          SEQNUM=1070
      - On a change of the config state of an zcrypt card device a new
        CHANGE uevent is sent with an env value CONFIG=<0|1>.
        Example uevent:
          KERNEL[876.258680] change	/devices/ap/card09 (ap)
          ACTION=change
          DEVPATH=/devices/ap/card09
          SUBSYSTEM=ap
          CONFIG=0			<- this is new
          DEVTYPE=ap_card
          DRIVER=cex4card
          DEV_TYPE=000D
          MODALIAS=ap:t0D
          MODE=cca
          SEQNUM=1073
        Setting a card config on/off causes the dependent queue devices to
        follow the config state change and thus uevents informing about the
        config state change for the queue devices are also emitted.
