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.

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.

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>

2007-10-10[NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger
Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted. Integrated Stephen's follow-on kerneldoc additions, and restored poll_list handling to the old style to fix mutual exclusion issues. -DaveM ] Signed-off-by: Stephen Hemminger <shemminger@linux-foundation.org> Signed-off-by: David S.
