2013-01-29[SCSI] qla4xxx: Fix MBOX intr switching from polling to intr mode for ISP83XXVikas Chaudhary1-11/+30
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.

QLogic applications store the CHAP information in FLASH. During login, authentication information is provided using an index into the CHAP region. In order to support QLogic applications along with iscsiadm, updated the LLD to not add duplicate CHAP entries in the CHAP region and preserve the existing CHAP info in the CHAP region in FLASH. This allows QLogic applications to pre-write the CHAP entries in the CHAP region. With iscsiadm, when the CHAP authentication information is sent to the LLD, the LLD searches for the entry in CHAP region in FLASH, if exists then do not add. If CHAP entry does not exist then add the CHAP entry in the CHAP region.
