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. Miller <davem@davemloft.net> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>
