2009-03-14netxen: add receive side scaling (rss) supportDhananjay Phadke
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.

2009-03-14netxen: remove old flash check.Dhananjay Phadke
Remove flash size check which made sense only for ancient boards with 1MB flash. The check is based on values read from specific locations and fails with firmware size changes.

2009-03-10netxen: annotate board_config and board_typeDhananjay Phadke
Remove huge board config structure from each instance, read only necessary fields from flash.

2009-02-24netxen: handle pci bar 0 mapping failureDhananjay Phadke
PCI bar 0 is used for memory mapped register access. If ioremap fails (returns NULL), register access results in crash. Use pci_ioremap_bar() instead of ioremap(), the latter fails on on 32 bit powerpc where pci resource address is > 32 bits.

2009-02-24netxen: fix physical port mappingDhananjay Phadke
The PCI function to physical port mapping is valid only for old firmware. New firmware (4.0.0+) abstracts this. So driver should never try to access phy using invalid mapping. The behavior is unpredictable when PCI functions 4-7 are enabled on the same NIC. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
