Enhancements to Debug infrastructure - debugfs additions for new hardware. - Correct stack overflow in lpfc_debugfs_dumpHBASlim_data() - Correct warning on uninitialized reg_val in lpfc_idiag_drbacc_write() - Separated the iDiag command for capturing mailbox commands for generic issue mailbox command entry point and for BSG multi-buffer handling. - Added capturing dumping capabiliy of mailbox command and external buffer for the completion of the mailbox command so that the outcome can be examined. - Changed all the iDiag command structure data array indexing introduced so far with properly defined macros. - Added SLI4 device PCI BAR memory mapped register read/browse, write-by- value, set-bit, and clear-bit methods for both interface type 0 and interface type 2. - Corrected warnings on mbxstatus being uninitialized in error paths in lpfc_bsg.c Signed-off-by: Alex Iannicelli <alex.iannicelli@emulex.com> Signed-off-by: James Smart <james.smart@emulex.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
