nvme-fc: Update header and host for common definitions for LS handling

2020-05-09T22:18:33Z

Given that both host and target now generate and receive LS's create a single table definition for LS names. Each tranport half will have a local version of the table. As Create Association LS is issued by both sides, and received by both sides, create common routines to format the LS and to validate the LS. Convert the host side transport to use the new common Create Association LS formatting routine.

nvmet-fc: Better size LS buffers

2020-05-09T22:18:33Z

Current code uses NVME_FC_MAX_LS_BUFFER_SIZE (2KB) when allocating buffers for LS requests and responses. This is considerable overkill for what is actually defined. Rework code to have unions for all possible requests and responses and size based on the unions. Remove NVME_FC_MAX_LS_BUFFER_SIZE.

nvme-fc nvmet-fc: refactor for common LS definitions

2020-05-09T22:18:33Z

Routines in the target will want to be used in the host as well. Error definitions should now shared as both sides will process requests and responses to requests. Moved common declarations to new fc.h header kept in the host subdirectory.
