Jens Remus 67496afe57 zdev: Report FC Endpoint Security of zfcp devices
Add support to report Fibre Channel (FC) Endpoint Security
related information for zfcp-host and zfcp-lun devices.

Allow to query (lszdev) and provide help for (chzdev) the FC Endpoint
Security capability of a FCP device (zfcp-host). Provide this
information by defining the FCP device attribute fc_security in zdev
zfcp-host.

Allow to query (lszdev) and provide help for (chzdev) the FC Endpoint
Security in use on a connection between a FCP device and a FC remote
port. Provide this information by introducing a virtual zdev zfcp-lun
attribute fc_security. It returns the fc_security attribute value of
the zfcp port object representing the FC remote port used to access the
LUN.
This approach allows users of lszdev to easily query the FC Endpoint
Security in use on the connections to one or more FCP LUNs. It also
does not require the effort to introduce a zfcp-port device type in
zdev.

The fc_security attribute help for both zfcp-host and zfcp-lun can be
queried for example as follows:

    chzdev zfcp --help-attribute

The fc_security attribute values and path of all active zfcp devices
can be queried for example as follows:

    lszdev zfcp -a -c TYPE,ID,ATTR:fc_security,ATTRPATH:fc_security
