       service_provider.conf - service provider configuration file


       service_provider.conf  contains  information about the device type that
       the service provider supports. This information includes  the  pathname
       of  the service provider library, the library version and other library
       characteristics that are required by the system administrative command,
       datadm(1M). datadm(1M) puts this information in the DAT static register
       file, dat.conf(4).

       The datadm program enumerates each device entry into a list  of  inter-
       face  adapters, that is, interfaces to external network that are avail-
       able to uDAPL  consumers.  This  new  list  of  interface  adapters  is
       appended to other service providers' information in the DAT static reg-
       istry, dat.conf. You can do this is you invoke the datadm program  with
       the -a option and the pathname of the service_provider.conf file.

       Each entry in the service_provider.conf is a single line of 7 fields.

       The  following shows the order of the fields in a service_provider.conf

       "driver_name" "API_version" "threadsafe_library | nonthreadsafe_library"\
       "default_version | nondefault_version" "service_provider_library_pathname"\
       "service_provider_version" "service_provider_instance_data"\

       The fields are defined as follows:


           Specifies a driver name in the format  of  driver_name=value  pair,
           for example, driver_name=tavor.


           Specifies the API version of the service provide library: For exam-
           ple, "u"major.minor is u1.2.

       threadsafe_library | nonthreadsafe_librar

           Specifies a threadsafe or non-threadsafe library.

       default_version | nondefault_version

           Specifies a default or non-default version of  library.  A  service
           provider can offer several versions of the library. If so, one ver-
           sion is designated as default with the rest as nondefault.


           Specifies the pathname of the library image.


           Specifies the version of the service provider. By convention, spec-
           ify  the  company stock symbol as the service provider, followed by
           major and minor version numbers, for example, SUNW1.0.


           Specifies the service provider instance data.

       Example 1: Using a Logical Device Name

       The following example service_provider.conf entry uses a logical device

       # Sample service_provider.conf entry showing an uDAPL 1.2 service
       # provider, udapl_tavor.so.1 supporting a device with a driver named tavor
       driver_name=tavor u1.2 nonthreadsafe default udapl_tavor.so.1 SUNW.1.0 ""

       Example 2: Using a Physical Device Name

       The  following  example  service_provider.conf  uses  a physical device

       # Sample service_provider.conf entry showing an uDAPL 1.2
       # service provider, udapl_tavor.so.1 supporting a device named
       # pci15b3,5a44 that can be located under /devices
       pci15b3,5a44 u1.2 nonthreadsafe default /usr/lib/tavor/udapl_tavor.so.1
       SUNWudaplt1.0 ""
