From 7b867cf76fbcc8d77867cbec6f509f71dce8a98f Mon Sep 17 00:00:00 2001 From: Anirban Chakraborty Date: Thu, 6 Nov 2008 10:40:19 -0800 Subject: [SCSI] qla2xxx: Refactor qla data structures Following changes have been made to the qla2xxx FC driver in preparation for the multi- queue and future SR IOV hardware. 1. scsi_qla_host structure has been changed to contain scsi host specific data only. 2. A new structure, qla_hw_data is created to contain HBA specific hardware data. 3. Request and response IO specific data strucures are created. 4. The global list of fcports for the hba is not maintained anymore, instead a fcport list is construted on per scsi_qla_host.
