d8b100c5da netxen: add receive side scaling (rss) support
This patch enables the load balancing capability of firmware
and hardware to spray traffic into different cpus through
separate rx msix interrupts.

The feature is being enabled for NX3031, NX2031 (old) will be
enabled later. This depends on msi-x and compatibility with
msi and legacy is maintained by enabling single rx ring.

438627c77b netxen: sanitize variable names
o remove max_ prefix from ring sizes, since they don't really
  represent max possible sizes.
o cleanup naming of rx ring types (normal, jumbo, lro).
o simplify logic to choose rx ring size, gig ports get half
  rx ring of 10 gig ports.

becf46a012 netxen: cleanup superfluous multi-context code
MAX_RCV_CTX was set to 1, there's only rx context per
PCI function.

9ad27643f3 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.

d9e651bc06 netxen: cut-through rx changes
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.
