[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.
