* [SCSI] bnx2fc: cleanup task management IO when it times out.Bhanu Prakash Gollapudi2012-05-221-0/+10
| | | | | | | | | When the task management IO times out, or a flush operation is performed while task management IO is pending, driver is not cleaning up the IO. This patch cleans up the IO for the above cases. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
* [SCSI] bnx2fc: Decrememnt io ref count when abort times outBhanu Prakash Gollapudi2012-05-221-1/+10
| | | | | | | | | | When IO abort times out during eh_abort or a flush operation is performed while abort is pending, the driver is not cleaning up the IO and thus not reducing the IO reference count. With this change, as part of explicit logout, the IO is cleaned up. Signed-off-by: Bhanu Prakash Gollapudi <bprakash@broadcom.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
* [SCSI] bnx2fc: Fix FW assert during RSCN stress testsBhanu Prakash Gollapudi2011-09-171-3/+1
| | | | | | | | | Firmware asserts when the same CQE is armed twice. This scenario happens during RSCN stress tests as driver incorrects arms the CQ after the session is offloaded.

* [SCSI] bnx2fc: code cleanup in bnx2fc_offload_sessionBhanu Prakash Gollapudi2011-08-271-4/+3
| | | | | | | | | | | - Free session resources before rport logoff - Do not free session resources in bnx2fc_alloc_session_resc() as it is handled in caller's error handling path. - Do not call bnx2fc_free_session_resc() if bnx2fc_init_tgt() fails as cq_lock is not yet initialized.

* [SCSI] bnx2fc: Fix NULL pointer deref during arm_cq.Bhanu Prakash Gollapudi2011-08-271-8/+11
| | | | | | | | | | | | There exists a race condition between CQ doorbell unmap and IO completion path that arms the CQ which causes a NULL dereference. Protect the ctx_base with cq_lock to avoid this. Also, wait for the CQ doorbell to be successfully mapped before arming the CQ. Also, do not count uncolicited CQ completions for free_sqes.

* [SCSI] bnx2fc: Do not reuse the fcoe connection id immediatelyBhanu Prakash Gollapudi2011-08-271-1/+0
| | | | | | | | | CFC_DELETE is issued 2 secs after CONN_TERM is completed. If the session is uploaded and offloaded immediately, it has to wait for the connection id to be available.

* [SCSI] bnx2fc: Introduce interface structure for each vlan interfaceBhanu Prakash Gollapudi2011-07-271-6/+11
| | | | | | | | | | | | | | | | | | 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>

* New 7.0 FW: bnx2x, cnic, bnx2i, bnx2fcVlad Zolotarov2011-06-151-5/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [SCSI] bnx2fc: Avoid holding cq_lock when iounmap() is calledBhanu Gollapudi2011-03-231-2/+2
| | | | | | | | | | | | | | | With kernel debugging enabled, holding cq_lock when calling bnx2fc_free_session_resc() which calls iounmap() leads to a warning stack trace [INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected]. iounmap() grabs a HARDIRQ-unsafe vmlist lock, so holding spin_lock_bh(cq_lock) when calling iounmap() will trigger the LOCKDEP warning. Since cq_lock is required only to guard against deletion, hold the lock just before freeing the cq.

* [SCSI] bnx2fc: Broadcom FCoE offload driverBhanu Gollapudi2011-02-281-0/+844
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.
