* [SCSI] qla2xxx: Fix array subscript is above array bounds in ↵Chad Dupuis2011-02-251-1/+1
| | | | | | | | | | | | | qla2xx_build_scsi_type_6_iocbs(). The additional increment of dsd_seg was causing the compiler to throw an array out of bounds warning. This patch moves to a direct assignment of cmd_pkt->fcp_data_dseg_len so that the compiler doesn't generate an array out bounds warning.

* [SCSI] qla2xxx: Added support for quiescence mode for ISP82xx.Saurav Kashyap2010-12-231-1/+131
| | | | | | | | | | | | | Support is added for quiescence mode. This feature is for P3P adapters. Any of the functions can put the firmware into quiescence state. All the others have to ack that request. During quiescence mode current commands are processed and all the new incoming I/Os are blocked. Loop resync is performed after firmware comes out of quiescence state.

This field is used during LUN reset cleanup and must match the field used in the FCP command.

* [SCSI] qla2xxx: Handle outstanding mbx cmds on hung f/w scenarios.Santosh Vernekar2010-07-271-1/+19
| | | | | | | | | | | | | | | | | | Outstanding mailbox commands, have no way to recover on f/w hung, and we timeout on waiting for mbx response. This in turn affects the recovery process as follows: - We might already be in dpc while waiting for mbx to complete, so recovery for that pci function will never get invoked. Reset Timeout (10 sec) is far less than mbx timeout (30 sec). - Other mbx cmds will get stuck due to serial mbx access. Solution is to identify fw-hung scenario and handle outstanding mbx commands to have an early-exit instead of waiting for response. Other mbx commands waiting for access will also do an early-exit if fw-hung is still applicable.
