6d7760a88c cnic: Fix ISCSI_KEVENT_IF_DOWN message handling.
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.

7cbdca23c8 Revert "[SCSI] cnic: fix error: implicit declaration of function ‘__symbol_get’"
This reverts commit bc3bf8fd33.

All the commit did was add a second #include of <linux/module.h> which is
the wrong fix.

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.
