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.

NX3031 supports cut-through operation where ingress packets are
directly dma'ed into host buffers to reduce latency.
This requires larger dma buffers (2kb) and different alignemnt.
The buffer posting logic is changed a bit. The free rx buffers
are maintained in linked list, since the received reference
handles can be out of order. However rx descriptors are still
posted sequentially, indexed by producer.
