[Stgt-devel] vtl patch.

[Mark Harvey]

Apologies for this being an attachment. It is rather large to include
inline (57k).

Follow up to feedback from earlier postings, I have implemented the following:


This patch includes the following changes.

- Patch to tgtadm so multiple '--name, --value' arguments can be passed.
- Add device_shutdown() & device_config() to device_type_template
- Unprocessed '--name, --value' arguments are passed to
device_config() in each device template to process.
- smc & ssc 'modules' (INQUIRY cmd implemented - more to come)

- Updated documentation in doc/README.vtl

NOTE: Many of the features in the doc/README.vtl are not implemented
and are included for comment. Better syntax ideas welcome.
