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.

when CONFIG_MODULES is not defined.  Fix by using symbol_get() instead.

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.
