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.

e125646ab5 netxen: revert jumbo ringsize
Reducing jumbo ring size below 1024 reduces throughput for old
firmwares (3.4.216 and older) running on older (NX2031) chip,
so restore it back to 1024.

This was reduced in commit 32ec803348
("netxen: reduce memory footprint").

Raising jumbo ring size from 512 to 1024, adds ~4MB per port, but
there's still big saving because of original patch (~20MB per port).

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.
