Subject: [PATCH 5/7] netxen: fix promisc mode, mtu setting
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.
