* [SCSI] qla4xxx: Take E-port out of reset before disabling pause framesManish Dusane2013-04-101-0/+28
| | | | | | | | | | | | | Problem Description: Disabling pause frames might cause hardware wedging needing a power cycle. This might happen if the Eport is not initialized and is in reset. Solution: Before disabling pause frames ensure that eport is out of reset.

* [SCSI] qla4xxx: Fix MBOX intr switching from polling to intr mode for ISP83XXVikas Chaudhary2013-01-291-13/+40
| | | | | | | | | | | | | | | | | | | | | | | | Issue: Mailbox command timed out after switching from polling mode to interrupt mode. Events:- 1. Mailbox interrupts are disabled 2. FW generates AEN and at same time driver enables Mailbox Interrupt 3. Driver issues new mailbox to Firmware In above case driver will not get AEN interrupts generated by FW in step #2 as FW generated this AEN when interrupts are disabled. During the same time driver enabled the mailbox interrupt, so driver will not poll for interrupt. Driver will never process AENs generated in step #2 and issues new mailbox to FW, but now FW is not able to post mailbox completion as AENs generated before are not processed by driver. Fix: Enable Mailbox / AEN interrupts before initializing FW in case of ISP83XX. This will make sure we process all Mailbox and AENs in interrupt mode.

* [SCSI] qla4xxx: Disable generating pause frames for ISP83XXTej Parkash2012-09-241-0/+144
| | | | | | | | | | | In case of FW hung ISP83XX generates continuous pause frames which causes switch to disable port. Added fix to disable generating pause frames in case of FW hung Signed-off-by: Tej Parkash <tej.parkash@qlogic.com> Signed-off-by: Vikas Chaudhary <vikas.chaudhary@qlogic.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
* [SCSI] qla4xxx: Fix double clearing of risc_intr for ISP83XXManish Dusane2012-09-241-1/+0
| | | | | | | | | | | | | | | Issue: For ISP83XX risc_intr getting clear two times in case of polling mode. risc_intr getting clear from interrupt_service_routine() as well from process_mbox_intr() because of this driver may clear risc_intr without processing interrupt. Fix: Do not clear risc_intr from process_mbox_intr().
