2009-12-11cnic: Zero out status block and Event Queue indices.Michael Chan1-0/+5
To prevent stale indices from causing spurious events when restarting the bnx2x devices. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-12-11cnic: Send delete command when shutting down iSCSI ring.Michael Chan1-0/+6
This step is necessary on the bnx2x devices when restarting the iSCSI ring. Without it, the firmware can assert and cause bnx2x to report errors. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-10-28cnic: Fix L2CTX_STATUSB_NUM offset in context memory.Michael Chan1-3/+3
The BNX2_L2CTX_STATUSB_NUM definition needs to be changed to match the recent firmware update: commit 078b0735881c7969aaf21469f3577831cddd9f8c bnx2: Update firmware to 5.0.0.j3. Without the fix, bnx2 can crash intermittently in bnx2_rx_int() when iSCSI is enabled.

2009-10-11cnic: Refactor some code.Michael Chan1-18/+46
Refactor ring init. code for subsequent 10G patches. Also add rtnl_lock() in cnic_uio_open() to prevent race condition with netdev events. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-10-02cnic: Fix NETDEV_UP event processing.Michael Chan1-1/+2
This fixes the problem of not handling the NETDEV_UP event properly during hot-plug or modprobe of bnx2 after cnic. The handling was skipped by mistakenly using "else if" to check for the event. Also update version to 2.0.1. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: Benjamin Li <benli@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-09-22cnic: Shutdown iSCSI ring during uio_close.Michael Chan1-2/+2
The iSCSI ring should be shutdown during uio_close instead of uio_open for proper operations. This fixes the problem of the ring getting stuck intermittently.

2009-08-15cnic: Fix locking in init/exit calls.Michael Chan1-9/+39
The slow path ulp_init and ulp_exit calls to the bnx2i driver are sleepable calls and therefore should not be protected using rcu_read_lock. Fix it by using mutex and refcount during these calls. cnic_unregister_driver() will now wait for the refcount to go to zero before completing the call.

2009-08-15cnic: Fix locking in start/stop calls.Michael Chan1-16/+28
The slow path ulp_start and ulp_stop calls to the bnx2i driver are sleepable calls and therefore should not be protected using rcu_read_lock. Fix it by using mutex and setting a bit during these calls. cnic_unregister_device() will now wait for the bit to clear before completing the call.

2009-08-15cnic: Refine registration with bnx2.Michael Chan1-13/+36
Register and unregister with bnx2 during NETDEV_UP and NETDEV_DOWN events. This simplifies the sequence of events and allows locking fixes in the next patch.

2009-08-15cnic: Fix symbol_put_addr() panic on ia64.Michael Chan1-1/+1
When the cnic driver tries to grab a symbol from bnx2 when bnx2 is running init code, symbol_get() will succeed but symbol_put_addr() will hit BUG() a moment later. module_text_address() fails because bnx2 is still in init code. This is fixed by using symbol_put() instead which does the exact opposite of symbol_get(). Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-07-27cnic: Fix ISCSI_KEVENT_IF_DOWN message handling.Michael Chan1-2/+21
When a net device goes down or when the bnx2i driver is unloaded, the code was not generating the ISCSI_KEVENT_IF_DOWN message properly and this could cause the userspace driver to crash. This is fixed by sending the message properly in the shutdown path. cnic_uio_stop() is also added to send the message when bnx2i is unregistering.

2009-06-09[SCSI] cnic: Add new Broadcom CNIC driver.Michael Chan1-0/+2711
The CNIC driver controls BNX2 hardware rings and resources used by iSCSI. Most hardware resources for iSCSI are separate from those used for ethernet networking. iSCSI uses a separate MAC address and IP address. The CNIC driver creates a UIO interface to handle the non-offloaded packets such as ARP, etc in userspace. Signed-off-by: Michael Chan <mchan@broadcom.com> Acked-by: David S.
