* [netdrvr] netxen: fix netxen_pci_tbl[] breakageAl Viro2008-06-271-7/+11
| | | | | | | | | | PCI_DEVICE_CLASS sets .device and .vendor to PCI_ANY_DEV, which overrides the effect of preceding PCI_DEVICE() and makes all elements of netxen_pci_tbl[] identical. Introduced in the commit dcd56fdbaeae1008044687b973c4a3e852e8a726. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

| | | | | | | | | | | | | | | | 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.

* netxen: napi and irq cleanupDhananjay Phadke2008-03-264-163/+48Star
| | | | | | | | | | | | | | | | 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.

* netxen: fix byte-swapping in tx and rxDhananjay Phadke2008-01-123-45/+40Star
| | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | 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.

* [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik2007-10-111-3/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | For the operations get-tx-csum get-sg get-tso get-ufo the default ethtool_op_xxx behavior is fine for all drivers, so we permit op==NULL to imply the default behavior. This provides a more uniform behavior across all drivers, eliminating ethtool(8) "ioctl not supported" errors on older drivers that had not been updated for the latest sub-ioctls. The ethtool_op_xxx() functions are left exported, in case anyone wishes to call them directly from a driver-private implementation -- a not-uncommon case. Should an ethtool_op_xxx() helper remain unused for a while, except by net/core/ethtool.c, we can un-export it at a later date.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-112-20/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | Instead of all drivers reading pci config space to get the revision ID, they can now use the pci_device->revision member. This exposes some issues where drivers where reading a word or a dword for the revision number, and adding useless error-handling around the read. Some drivers even just read it for no purpose of all. In devices where the revision ID is being copied over and used in what appears to be the equivalent of hotpath, I have left the copy code and the cached copy as not to influence the driver's performance.
