The driver fails to allocate command buffers in the routine lpfc_new_scsi_buf_s4 There is an inconsistency between lpfc_mem_alloc(), where the phba->lpfc_sg_dma_buf_pool is created, and lpfc_new_scsi_buf_s4(), when we allocate a buffer from the pool and check the alignment. The alignment should be on a page boundary, based on LPFC_SLI3_BG_ENABLED in sli3_options, for both cases. Fix by explicitly tracking sli4 vs sli3 and BG options. The result is that phba->cfg_sg_dma_buf_size is now set correctly for SLI-4.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
