2ba451421b bnx2x, cnic: Consolidate iSCSI/FCoE shared mem logic in bnx2x
Move all shared mem code to bnx2x to avoid code duplication.  bnx2x now
performs:

- Read the FCoE and iSCSI max connection information.
- Read the iSCSI and FCoE MACs from NPAR configuration in shmem.
- Block the CNIC for the current function if there is neither FCoE nor
  iSCSI valid configuration by returning NULL from bnx2x_cnic_probe().

42bb8d5695 cnic: Do not call bnx2i when bnx2i is calling cnic_unregister_driver()
We should call bnx2i to send the iSCSI netlink message earlier in
cnic_unregister_device().  By the time cnic_unregister_driver() is
called, bnx2i may have freed data structures used by the upcalls.

Update version to 2.2.12.

939b82e5bd cnic: Improve ->iscsi_nl_msg_send()
1. Change first parameter from cnic_dev to ulp_handle which is the hba
pointer.  All other similar upcalls are using hba pointer.  The callee
can then directly reference the hba without conversion.

2. Change return value from void to int so that an error code can be
passed back.  This allows the operation to be retried.

This is the new FW HSI blob and the relevant definitions without logic changes.
It also included code adaptation for new HSI. New features are not enabled.

New FW/HSI includes:
- Support for 57712 HW
- Future support for VF (not used)
- Improvements in FW interrupts scheme
- FW FCoE hooks (stubs for future usage)

b58ffb41fc cnic: Fix context memory init. on 5709.
We need to zero context memory on 5709 in the function cnic_init_context().
Without this, iscsid restart on 5709 will not work because of stale data.
TX context blocks should not be initialized by cnic_init_context() because
of the special remapping on 5709.

Update version to 2.1.2.

6053bbf7bb cnic: Fix NETDEV_UP event processing.
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.

7fc1ece407 cnic: Fix locking in init/exit calls.
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.

a463696039 [SCSI] cnic: Add new Broadcom CNIC driver.
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.
