bnx2x: Receive traffic that maches management filtering rules

Due to lack of configuration, if the BMC configures the chip to pass all
broadcast/multicast traffic to it, the host will not receive it. On top of
fixing it, also make sure that in promiscuous mode, the host will receive the
management traffic as well.
