2009-04-08netxen: enable rss for NX2031Dhananjay Phadke
Enable multiple rx rings for older NX2031 chip, firmware 3.4.336 or newer supports this feature. Signed-off-by: Amit Kumar Salecha <amit@netxen.com> Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-04-08netxen: sanitize function namesDhananjay Phadke
Replace superfluous wrapper functions with two macros: NXWR32 replaces netxen_nic_reg_write, netxen_nic_write_w0, netxen_nic_read_w1, netxen_crb_writelit_adapter. NXRD32 replaces netxen_nic_reg_read, netxen_nic_read_w0, netxen_nic_read_w1. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-04-08netxen: annotate register access functionsDhananjay Phadke
o remove unnecessary length parameter since register access width is fixed 4 byte. o remove superfluous pci_read_normalize and pci_write_normalize functions. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-04-08netxen: refactor transmit codeDhananjay Phadke
o move tx stuff into nx_host_tx_ring structure, this will help managing multiple tx rings in future. o sanitize some variable names Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-04-08netxen: refactor netxen_adapterDhananjay Phadke
Rearrange members to align them at right offset. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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: sanitize variable namesDhananjay Phadke
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.

2009-03-10netxen: cleanup superfluous multi-context codeDhananjay Phadke
MAX_RCV_CTX was set to 1, there's only rx context per PCI function. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-02-27netxen: update copyrightDhananjay Phadke
Extend copyright into 2009 and update address. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-01-14netxen: fix endianness in firmware commandsDhananjay Phadke
o Set restricted (little endian) data types in firmware command requests and responses. o Remove unnecessary conversion to LE when writing registers. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-07netxen: fix promisc mode, mtu settingDhananjay Phadke
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.

2008-07-22netxen: cut-through rx changesDhananjay Phadke
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. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
