* [SCSI] bfa: cleanup driverKrishna Gudipati2010-09-16101-14144/+0
| | | | | | | | We have flattened the BFA hierarchy and also reduced the number of source and header files we used to have earlier. Signed-off-by: Krishna Gudipati <kgudipat@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>

* [SCSI] bfa: update to support BOFMJing Huang2010-07-273-3/+17
| | | | | | | | Update bfa driver API and data structure to support BOFM (IBM BladeCenter Open Fabric Manager). Signed-off-by: Jing Huang <huangj@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
* [SCSI] bfa: fix link state structureJing Huang2010-07-271-19/+3
| | | | | | | | | | | | | | When the FCoE Linkup event is sent to the host, the link_state (struct bfa_pport_link_s) structure is copied to the RME buf to be sent to the host. But the size of this structure(164 bytes) is larger than the reserved RME buffer size(128 byes). The following changes reduce the size of the structure to be less than RME buffer size(128 bytes): - Remove the trunk and loop info from link_state structure, because both trunk and loop are not supported. - Combine qos_vc_attr and fcf into an union.

* [SCSI] bfa: add dynamic queue selectionJing Huang2010-07-273-2/+21
| | | | | | | | Add new bfa functionality to support dynamic queue selection (IO redirection). IO redirection can only be enabled when QoS is disabled. Signed-off-by: Jing Huang <huangj@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
* [SCSI] bfa: fix uf post and rport fcpim state machineJing Huang2010-07-271-0/+1
| | | | | | | | | | | | BFA UF module did not hold lock when seding uf post buffer message to firmware causing CPE-Q corruption. Fix is to check present of FCS and if FCS present hold lock while posting UF buffers. Handle PRLO with sending acc to it and relogin with rport. Discard fcxp before any state change.

* [SCSI] bfa: fix chip and memory initializationJing Huang2010-07-271-0/+3
| | | | | | | | | | Clear PSS memory reset that is set as part of power-on-reset (pci reset). Complete PMM memory reset before BISTR start. Clear EDRAM BISTR start bit after fixed delay. BISTR DONE bit status is not getting set. Use a fixed 1ms delay for BISTR now. Expose PMM IT memory definitions to host.

* [SCSI] bfa: fix prli retry issuesJing Huang2010-07-271-0/+1
| | | | | | | | | | Add a max retry limit for PRLI retries. Max retry limit (5) is same as used in rport PLOGI. Once the retries are exhausted, invoke rport offline so that existing logic of rport re-discovery can kick-in. Also fixed a bug in rport.c where one less retry was happening.
