cnic: Support NIC Partition mode
Add a common function cnic_read_bnx2x_iscsi_mac() to read the iSCSI MAC address at any specified shared memory location. In NIC Partition mode, we need to get the MAC address from the MF_CFG area of shared memory. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
