2009-10-28cnic: Fix L2CTX_STATUSB_NUM offset in context memory.Michael Chan
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 Chan
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 Chan
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 Chan
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 Chan
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 Chan
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 Chan
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 Chan
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 Chan
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 Chan
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.
