* [ETHTOOL] Provide default behaviors for a few ethtool sub-ioctlsJeff Garzik2007-10-101-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | 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 Hemminger2007-10-101-25/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [BNX2]: Fix suspend/resume problem.Michael Chan2007-08-031-4/+8
| | | | | | | | | | | | | | | The device would not resume properly if it was shutdown before the system was suspended. In such scenario where the netif_running state is 0, bnx2_suspend() would not save the PCI state and so the memory enable bit and bus master enable bit would be lost. We fix this by always saving and restoring the PCI state in bnx2_suspend() and bnx2_resume() regardless of netif_running() state. Update version to 1.6.4.

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

This is needed during netpoll where the timer is not available. -rt kernels will also benefit since the timer is not as accurate.

* | [BNX2]: Reduce spurious INTA interrupts.Michael Chan2007-07-101-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Spurious interrupts are often encountered especially on systems using the 8259 PIC mode. This is because the I/O write to deassert the interrupt is posted and won't get to the chip immediately. As a result, the IRQ may remain asserted after the IRQ handler exits, causing spurious interrupts. Add read back to flush the I/O write to deassert the IRQ immediately. We also store the last_status_idx immediately in the IRQ handler to help detect whether the interrupt is ours or not when the IRQ is entered again before ->poll gets called.

This patch adds the logic to interface with the firmware to control the remote PHY autonegotiation and to handle remote PHY link events. When remote PHY is present, the 5708S Serdes device practically becomes a copper device with full control over the 1000Base-T link settings.

| | | | | | | | | | | | | | | | | | | | | | The statistics block DMA on 5708 can be messed up occasionally on the average of about once per hour. If the user is reading the counters within one second after the corruption, the counters will be all messed up. One second later, the counters will be ok again until the next corruption occurs. The workaround is to disable the periodic statistics DMA. Instead, we manually trigger the DMA once a second in bnx2_timer(). This manual trigger of the DMA avoids the problem. As a consequence, we can only allow 0 or 1 second settings for ethtool -C statistics block. Thanks to Jean-Daniel Pauget <jd@disjunkt.com> and CaT <cat@zip.com.au> for reporting this rare problem.
