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: annotate board_config and board_typeDhananjay Phadke
Remove huge board config structure from each instance, read only necessary fields from flash. Replace board_type with port_type (1G/10G), there's another board_type field describing card type (SFP/XFP/CX4). Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-01-14netxen: firmware init fixDhananjay Phadke
o Fix order or rom register writes. o Reduce udelays when writing rom registers. This cuts the firmware init time by 40%. o Do not reset core/memory clocks when reinitializing driver. Firmware willl handle this when initialized. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-11-03drivers/net: Kill now superfluous ->last_rx stores.David S. Miller
The generic packet receive code takes care of setting netdev->last_rx when necessary, for the sake of the bonding ARP monitor. Drivers need not do it any more. Some cases had to be skipped over because the drivers were making use of the ->last_rx value themselves. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-08-14netxen: fix dma watchdogDhananjay Phadke
NX3031 does not require driver to kill dma watchdog. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
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>
2008-07-22netxen: mtu, mac, link status changesDhananjay Phadke
MAC addr, multicast filters, mtu are set through firmware commands in firmware v4.0.0+ because of virtualization of physical ports. Link status is also read from registers allocated by firmware for each virtual port. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-07-22netxen: cleanup unused variables/functionsDhananjay Phadke
o Reduce access to global arrays in data path. o Remove duplicate/unused variables, unecessary alignment constraints. o Use correct pci_dev instead of fallback device for consistent allocations. o Disable ethtool set_eeprom functionality for now, it was only used for flashing firmware.

2008-03-25netxen: fix rx dropped statsDhananjay Phadke

2008-03-25netxen: remove low level tx lockDhananjay Phadke
o eliminate tx lock in netxen adapter struct, instead pound on netdev tx lock appropriately. o remove old "concurrent transmit" code that unnecessarily drops and reacquires tx lock in hard_xmit_frame(), this is already serialized the netdev xmit lock. o reduce scope of tx lock in tx cleanup. tx cleanup operates on different section of the ring than transmitting cpus and is guarded by producer and consumer indices. This fixes a race caused by rx softirq preemption on realtime kernels.

2008-03-25netxen: napi and irq cleanupDhananjay Phadke
o separate and simpler irq handler for msi interrupts, avoids few checks than legacy mode. o avoid redudant tx_has_work() and rx_has_work() checks in interrupt and napi, which can uncork irq based on racy (lockless) access to tx and rx ring indices. If we get interrupt, there's sufficient reason to schedule napi. o replenish rx ring more often, remove self-imposed threshold rcv_free that prevents posting rx desc to card. This improves performance in low memory. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Tested-by: Vernon Mauery <mauery@us.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-03-25netxen: improve msi supportDhananjay Phadke
Recent netxen firmware has new scheme of generating MSI interrupts, it raises interrupt and blocks itself, waiting for driver to unmask. This reduces chance of spurious interrupts. The driver will be able to deal with older firmware as well.

2008-01-12netxen: fix byte-swapping in tx and rxDhananjay Phadke
Here's the reworked patch. This cleans up some unnecessary byte-swapping while setting up tx and interpreting rx desc. The 64 bit rx status data should be converted to host endian format only once and the macros just need to extract bitfields. This saves a spate of interrupts on pseries blades caused by buggy (non) processing rx status ring. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2008-01-12netxen: optimize tx handlingdhananjay@netxen.com
netxen driver allows limited number of threads simultaneously posting skb's in tx ring. If transmit slot is unavailable, driver calls schedule() or loops in xmit_frame(). This patch returns TX_BUSY and lets the stack reschedule the packet if transmit slot is unavailable. Also removes unnecessary check for tx timeout in the driver itself, the network stack does that anyway.
