* [SCSI] bfa: Add FC-transport based Asynchronous Event Notification support.Krishna Gudipati2011-07-271-0/+26
| | | | | | | | - Added support to post vendor unique events on fc_host. - Supports adapter, port, ioc, flash and remote port based AEN events. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
* [SCSI] bfa: FCS bug fixes.Krishna Gudipati2011-06-291-5/+15
| | | | | | | | | | | | | | | | | | | | | | - Added logic to initiate a PLOGI to the target, while processing a LOGO from the same target in Direct attach mode. - Added logic to generate a FCCT Reject indicating unsupported command, upon receiving FCCT/FCGS requests. - Added logic to set the fcpim in offline state and avoid any PRLI retries if a PRLI response is a reject with a reason Command Not Supported. - Updated the FDMI Supported/Current speeds. - Added logic to wait for the response from the firmware before sending ACC to PLOGI and transitioning to subsequent states - while processing an Incoming PLOGI in online state. - Added a wait state in the fcs_vport state machine - For case where FDISC is in progress and we get a vport delete request we wait for fdisc response and will transition to the appropriate state based on rsp status, else its causing both driver/fw resources to be not freed. - Remove the fc_credit_recovery module param.

* [SCSI] bfa: Brocade-1860 Fabric Adapter vHBA support.Krishna Gudipati2011-06-291-1/+1
| | | | | | | | | | | | | | | | | | - Introduced partitioning of the BFA resources. - Added h/w queue ID in CPE messages, firmware uses h/w queue ID from messages to pick a matching RME queue. - Added message header to bfa_reqq_produce(). h/w queue ID is set in the message header and firmware modules use h/w queue ID from message header instead of from cpqe event. - Made changes to allow using all 256 queues of Brocade-1860 asic. Previously only a single queue per queue group was used. - Added function tag to BFI message header. Only used by FC BFI messages. Used to translate host tag to firmware tag. bfa_lpuid() is changed to bfa_fn_lpu() that encodes both PCI function and port ID in BFI message header.

* [SCSI] bfa: Add BSG interface to support ELS, CT and vendor commands.Krishna Gudipati2011-06-291-0/+39
| | | | | | | | | - Added BSG interface support to BFA driver - Adds support to send ELS/CT FC passthru commands and few vendor specific BSG requests. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
* [SCSI] bfa: Driver initialization and model description fixKrishna Gudipati2011-06-291-4/+28
| | | | | | | | | | | | | | - Moved FCS initialization, which internally does the im_port creation as well as the scsi_host creation before bfa_init. Once the bfa_init is complete & successful: - Reset the FCS base port cfg params such as pwwn/nwwn and setup fc host params - based on the values learned during the ioc getattr request. - Change needed to support BSG commands even on bfa init failure. - Model description fixes for Brocade adapters.

* [SCSI] bfa: FC credit recovery and misc bug fixes.Krishna Gudipati2011-06-291-6/+54
| | | | | | | | | | | | | | | | - Introduce FC credit recovery. - Added module parameter to enable/disable credit recovery. Bug Fixes: - Removed check for ignoring plogi from initiator in switched fabric mode. - The ABTS for PLOGI is going out few millisecs earlier due to FW timer calibration (around 300 miilisecs earlier). So there is a window if an accept comes during this time HBA would have initiated an ABORT. - Added 1 to FC_ELS_TOV for compensating for FW timer.

* | [SCSI] bfa: PBC vport createJing Huang2010-07-271-1/+9
|/ | | | | | | | | | | This patch enables creating PBC vport. During fcs init, fcs will read PBC vport using bfa iocfc API and invoke fcb callback to add the pbc vport entries into a list. The pbc vport list will be traversed in the subsequent pci probe process and vport will be created using fc transport provided vport create function.
