2016-08-24scsi: be2iscsi: Fix to make boot discovery non-blockingJitendra Bhivare1-4/+14
Boot work involves: 1. Find and fetch configured boot session and its handle. 2. Attempt to open the session if its not. 3. Get the session details for boot kset creation. 4. Logout of that session owned by FW. 5. Create boot kset for session details. All these actions were done in blocking call with retries in global wq. Other works in wq suffered if the IOCTLs stalled or timed out. This change moves all the boot work to make it non-blocking. The work queued in global wq just issues the IOCTL depending on the action to be taken and mcc wq schedules work depending on status of the IOCTL. Initial boot_work is started on link and ASYNC event. The other code changes move all boot related functions in one place and follow naming conventions.
