From 76a95d75ede64e4f1684ddb8c626fdfdb641bda2 Mon Sep 17 00:00:00 2001 From: James Smart Date: Sat, 20 Nov 2010 23:11:48 -0500 Subject: [SCSI] lpfc 8.3.19: Add SLI4 FC Discovery support Add SLI4 FC Discovery support - Replace READ_LA and READ_LA64 with READ_TOPOLOGY mailbox command. - Converted the old READ_LA structure to use bf_set/get instead of bit fields. - Rename HBA_FCOE_SUPPORT flag to HBA_FCOE_MODE. Flag now indicates function is running as SLI-4 FC or FCoE port. Make sure flag reset each time READ_REV completed as it can dynamically change. - Removed BDE union in the READ_TOPOLOGY mailbox command and added a define to define the ALPA MAP SIZE. Added FC Code for async events. - Added code to support new 16G link speed. - Define new set of values to keep track of valid user settable link speeds. - Used new link speed definitions to define link speed max and bitmap. - Redefined FDMI Port sppeds to be hax values and added the 16G value. - Added new CQE trailer code for FC Events. - Add lpfc_issue_init_vfi and lpfc_init_vfi_cmpl routines. - Replace many calls to the initial_flogi routine with lpfc_issue_init_vfi. - Add vp and vpi fields to the INIT_VFI mailbox command. - Addapt lpfc_hba_init_link routine for SLI4 use. - Use lpfc_hba_init_link call from lpfc_sli4_hba_setup. - Add a check for FC mode to register the FCFI before init link. - Convert lpfc_sli4_init_vpi to be called without a vpi (get it from vport).
