bnx2x: Add Nic partitioning mode (57712 devices)
NIC partitioning is another flavor of multi function - having few PCI functions share the same physical port. Unlike the currently supported mode of multi-function which depends on the switch configuration and uses outer-VLAN, the NPAR mode is switch independent and uses the MAC addresses to distribute incoming packets to the different functions. This patch adds the specific HW setting of the NPAR mode and some distinctions between switch dependent (SD) and switch independent (SI) multi-function (MF) modes where the configuration is not the same. Advance driver version to 1.60.00-6 Signed-off-by: Dmitry Kravkov <dmitry@broadcom.com> Signed-off-by: Eilon Greenstein <eilong@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
