2012-05-23[SCSI] bnx2fc: Allocate fcoe_ctlr with bnx2fc_interface, not as a memberRobert Love1-1/+1
Currently the fcoe_ctlr associated with an interface is allocated as a member of struct bnx2fc_interface. This causes problems when when later patches attempt to use the new fcoe_sysfs APIs which allow us to allocate the bnx2fc_interface as private data to a fcoe_ctlr_device instance. The problem is that libfcoe wants to be able use pointer math to find a fcoe_ctlr's fcoe_ctlr_device as well as finding a fcoe_ctlr_device's assocated fcoe_ctlr. To do this we need to allocate the fcoe_ctlr_device, with private data for the LLD. The private data will contain the fcoe_ctlr and its private data will be the bnx2fc_interface. +-------------------+ | fcoe_ctlr_device | +-------------------+ | fcoe_ctlr | +-------------------+ | bnx2fc_interface | +-------------------+ This prep work will allow us to go from a fcoe_ctlr_device instance to its fcoe_ctlr as well as from a fcoe_ctlr to its fcoe_ctlr_device once the fcoe_sysfs API is in use (later patches in this series).

2012-05-22[SCSI] bnx2fc: Allow FLOGI to be retried when receiving bad responses.Bhanu Prakash Gollapudi1-13/+3
Commit 907c07d45199f954ddcf66c2c9763c87d012cb15 added more cases to do FLOGI retry on receiving bad response. Remove the code that drops the packet and allow the stack to handle bad FLOGI response.

2011-10-30[SCSI] bnx2fc: Handle SRR LS_ACC drop scenarioBhanu Prakash Gollapudi1-11/+12
When SRR LS_ACC is dropped, the driver was not issuing ABTS for SRR when it times out. Since the target received SRR, it was able to send the XFER_RDY and the the original IO request completed successfully. In this condition ABTS was not sent during bnx2fc_srr_compl(). Fix this by first checking for ELS timeout and issue ABTS before checking if original IO request is complete.

2011-09-17[SCSI] bnx2fc: No abort issued for REC when it times outBhanu Prakash Gollapudi1-12/+14
ABTS was not issued for timed out REC, as REC completion handler exits out if the IO completed. Check for timed out REC and issue ABTS before proceeding with further processing in REC completion handler. Also, initialize rec_retry and srr_retry before starting the IO.

2011-07-28[SCSI] bnx2fc: Support 'sequence cleanup' taskBhanu Prakash Gollapudi1-0/+20
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 Gollapudi1-4/+5
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>

2011-06-15New 7.0 FW: bnx2x, cnic, bnx2i, bnx2fcVlad Zolotarov1-3/+4
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.

2011-03-01[SCSI] bnx2fc: Broadcom FCoE offload driverBhanu Gollapudi1-0/+515
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.
