Michael Chan	681dbd7107	cnic: Fix locking in start/stop calls. ... 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.

Michael Chan	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. Signed-off-by: Michael Chan <mchan@broadcom.com> Acked-by: David S.
