NVME Initiator: Base modifications
This is part E of parts A..F.
Part E is limited to lpfc_sli.c. This is the location of most of changes
for the following:
- sli3 ring vs sli4 wq splits
- io abort interfaces
- actual queuing routines and use of dma and sgl pools
- service routines to create/delete queues
*********
Refer to Part A for a description of base modifications
