bnx2: Support secondary MAC addresses.
Add support for configuring secondary unicast addresses. There
are 4 additional perfect match filters which can be used for
secondary unicast address support.
* Modified bnx2_set_mac_addr() to be more generic in handling
the setting of the perfect match filters
* Changed bnx2_set_rx_mode() to handle the unicast dev_addr_list
