2011-07-28[SCSI] bnx2fc: Support 'sequence cleanup' taskBhanu Prakash Gollapudi
For the devices that support sequence level error recovery, based on the REC response, the firmware has to be informed about the offset from which the retransmission should happen. Driver initiates sequence cleanup task to firmware so that the firmware can program the task. Upon the sequence cleanup completion, SRR is issued to retransmit the sequence.

2011-07-27[SCSI] bnx2fc: Introduce interface structure for each vlan interfaceBhanu Prakash Gollapudi
Currently, bnx2fc has a hba structure that can work with only a single vlan interface. When there is a change in vlan id, it does not have the capability to switch to different vlan interface. To solve this problem, a new structure called 'interface' has been introduced, and each hba can now have multiple interfaces, one per vlan id. Most of the patch is a moving the interface specific fields from hba to the interface structure, and appropriately modifying the dereferences. A list of interfaces (if_list) is maintained along with adapter list. During a create call, the interface structure is allocated and added to if_list and deleted & freed on a destroy call. Link events are propagated to all interfaces belonging to the hba. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>

2011-06-29[SCSI] bnx2fc: Fix kernel panic when deleting NPIV portsBhanu Prakash Gollapudi
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.

2011-06-15New 7.0 FW: bnx2x, cnic, bnx2i, bnx2fcVlad Zolotarov
New FW/HSI (7.0): - Added support to 578xx chips - Improved HSI - much less driver's direct access to the FW internal memory needed. New implementation of the HSI handling layer in the bnx2x (bnx2x_sp.c): - Introduced chip dependent objects that have chip independent interfaces for configuration of MACs, multicast addresses, Rx mode, indirection table, fast path queues and function initialization/cleanup. - Objects functionality is based on the private function pointers, which allows not only a per-chip but also PF/VF differentiation while still preserving the same interface towards the driver. - Objects interface is not influenced by the HSI changes which do not require providing new parameters keeping the code outside the bnx2x_sp.c invariant with regard to such HSI chnages. Changes in a CNIC, bnx2fc and bnx2i modules due to the new HSI.

2011-03-23[SCSI] bnx2fc: common free list for cleanup commandsBhanu Gollapudi
Cleanup commands are issued to the firmware to cleanup any stuck ios that are supposed to be implicitly aborted. In the worst case we can have all scsi ios filling up the free_list and we may not be able to allocate cleanup tasks. So the driver has to reserve free_list entries to be able to allocate the cleanup tasks. This reserve free_list common to all cpus is allocated as one additional entry in the per cpu free_lists. In bnx2fc_cmd_alloc(), there is a related fix to use get_cpu() for the free_list_index. This will prevent using the wrong index if the CPU is preempted.

2011-02-28[SCSI] bnx2fc: Broadcom FCoE offload driverBhanu Gollapudi
This driver is for Broadcom Netxtreme II 57712 chip. The following patch contains the driver sources for bnx2fc driver. libfc/libfcoe changes to enable bnx2fc have already gone through the fcoe tree. bnx2fc is a SCSI low level driver that interfaces with SCSI midlayer, libfc, libfcoe, cnic modules. bnx2fc driver uses services of libfc for slow path operations such as FIP and fabric discovery. The fast path IO perations are performed after offloading the session information to the underlying FCoE firmware.
