The fcoe driver can implement ddp_targ() similarly to ddp_setup() when fcoe stack works with existing target frame, e.g., tcm, where the ddp_targ() would eventually point to the underlying hardware driver's implementation of ndo_fcoe_ddp_targ() through net_device_ops. This new API sets up DDP context for target appropriately by setting required bits for DDP context.

Problem: Existing RPORT state machine continues witg FLOGI/PLOGI process only after it receices beacon from other end. Once claiming stage is over (either clain notify or clain repose), beacon is sent and state machine enters into operational mode where it initiates the rlogin process (FLOGI/PLOGI) to the peer but before this rlogin is initiated, exitsing implementation checks if it received beacon from other end, it beacon is not received yet, rlogin process is not initiated. Other end initiates FLOGI but peer end keeps on rejecting FLOGI, hence after 3 retries other end deletes associated rport, then sends a beacon. Once the beacon is received, peer end now initiates rlogin to the peer end but since associated rport is deleted FLOGI is neither accepted nor the reject response send out because rport is deleted. Hence unable to proceed withg FLOGI/PLOGI process and fails to establish VN2VN connection. Fix: VN2VN spec is not standard yet but based on exitsing collateral on T11, it appears that, both end shall send beacon and enter into 'operational mode' without explictly waiting for beacon from other end. Fix is to allow the RPORT login process as long as respective RPORT is created (as part of claim notification / claim response) even though state of RPORT is INIT. Means don't wait for beacon from peer end, if peer end initiates FLOGI (means peer end exist and responding). Notes: This patch is preparing the FCoE stack for target wrt offload. This is generic patch and harmless even if applied on storage initiator because 'else if' condition of function 'fcoe_oem_found' shall evaluate to TRUE only for targets.

struct scsi_lun is also just a struct with an array of 8 octets (64 bits) but using it instead in iscsi structs lets us call scsilun_to_int without a cast, and also lets us copy it using assignment, instead of memcpy().

Properly handling of target reset in multi-initiator environment Clean up in broadcast change handling: (1) Need to look at the status of each task management request, and retry the TM when there are failures. (2) Need quiescence IO so the driver doesn't take on more IO request while it's in the middle of sending TM request to firmware (3) Add support to keep track of how many pending broadcast AEN events are received while the broadcast handling is active, then loop back at the end of this routine if there were any events received. Clean up in mpt2sas_scsih_issue_tm routine: (1) Make sure proper status is returned when host reset fails (2) Clean up sanity checks near end of routine, insuring all outstanding IOs were completed.

This feature is to override the default max_sectors setting at load time, taking max_sectors as an command line option when loading the driver. The setting is currently hard-coded in the driver to 8192 sectors (4MB transfers). If max_sectors is specified at load time, minimum specified setting will be 64, and the maximum is 8192. The driver will modify the setting to be on even boundary. If max_sectors is not specified, the driver will default to 8192.

mpt2sas driver revision q header update: (1) Modified the descriptions of the LocalAddress bit in the Flags field of the MPI SGE Format description and the MPI Simple Element. (2) Modified Data Location Address Space bits in the Flags field of the IEEE Chain Element. (3) Added more detail to the description of the DataLength field for the SCSI IO Request and Target Assist Request. Removed restriction on using chained SGLs when using multicast or bidirectional support. (4) In Manufacturing Page 7, added ReceptacleID field to ConnectorInfo, and reworked how the Pinout field is used. (5) In IO Unit Page 7, added BoardTemperature and BoardTemperatureUnits fields. (6) In IOC Page 1, changed CoalescingTimeout to units of half-microsecond and updated descriptions. (7) Modified descriptions of SATASlumberTimeout and SASSlumberTimeout fields in SAS IO Unit Page 5 to indicate the timers start after partial mode is entered. (8) Added Extended Manufacturing configuration pages. Signed-off-by: NKashyap Desai <kashyap.desai@lsi.com> Signed-off-by: NJames Bottomley <JBottomley@Parallels.com>

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.

Deleting NPIV port causes a kernel panic when the NPIV port is in the same zone as the physical port and shares the same LUN. This happens due to the fact that vport destroy and unsolicited ELS are scheduled to run on the same workqueue, and vport destroy destroys the lport and the unsolicited ELS tries to access the invalid lport. This patch fixes this issue by maintaining a list of valid lports and verifying if the lport is valid or not before accessing it.
