netxen: fix promisc mode, mtu setting

Browse source 
For NX3031, multicast filtering, promisc mode, and max frame size
setting is handled by firmware, driver needs to send request to
enable/disable it.

For old chip revisions / firmware, driver still sets it directly.

Added function pointer to set mtu according to chip revision.
