* pasemi_mac: basic ethtool supportOlof Johansson2008-03-05
| | | | | | | First cut at ethtool support, to be completed over time. Signed-off-by: Olof Johansson <olof@lixom.net> Acked-by: Jeff Garzik <jgarzik@pobox.com>
* pasemi_mac: jumbo frame supportOlof Johansson2008-03-05
| | | | | | | | | | | | | | First cut at jumbo frame support. To support large MTU, one or several separate channels must be allocated to calculate the TCP/UDP checksum separately, since the mac lacks enough buffers to hold a whole packet while it's being calculated. Furthermore, it seems that a single function channel is not quite enough to feed one of the 10Gig links, so allocate two channels for XAUI interfaces.

* pasemi_mac: add support for setting MTUOlof Johansson2008-02-03
| | | | | | | | | Currently keeping it at 1500 bytes or below since jumbo frames need special checksum offload on TX. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S. Miller <davem@davemloft.net>

* pasemi_mac: Fix TX cleaningOlof Johansson2008-01-28
| | | | | | | | | | | | | | | | | pasemi_mac: Fix TX cleaning This is a bit awkward. We don't have a timer-delayed interrupt on TX complete, but we have a count threshold. So set that reasonably high (32 packets), and schedule the NAPI poll when it goes off. Also bump a regular timer that will take care of rotting packets for the last 1..31 ones in case we don't trigger a TX interrupt (and there's no RX activity that would otherwise trigger the poll). The longer-term fix is to separate TX from RX NAPI and do two separate poll loops. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* pasemi_mac: Convert to new dma libraryOlof Johansson2008-01-28

This also does a couple of other minor cleanups w.r.t. channel management. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* pasemi_mac: Move register definitions to include/asm-powerpcOlof Johansson2008-01-28
| | | | | | | | | | | | | | pasemi_mac: Move register definitions to include/asm-powerpc Move the common register formats and descriptor layouts from drivers/net/pasemi_mac.h to include/asm-poewrpc/pasemi_dma.h Previously only the ethernet driver was using them, but other drivers are coming up that will also use them, so it makes sense to share the constants.

* pasemi_mac: enable iommu supportOlof Johansson2007-10-10
| | | | | | | | | | | | | pasemi_mac: enable iommu support Enable IOMMU support for pasemi_mac, but avoid using it on non-partitioned systems for performance reasons. The user can override this by selecting the PPC_PASEMI_IOMMU_DMA_FORCE configuration option. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>
* pasemi_mac: use buffer index pointer in clean_rx()Olof Johansson2007-10-10
| | | | | | | | | | | | | | | | | pasemi_mac: use buffer index pointer in clean_rx() Use the new features in B0 for buffer ring index on the receive side. This means we no longer have to search in the ring for where the buffer came from. Also cleanup the RX cleaning side a little, while I was at it. Note: Pre-B0 hardware is no longer supported, and needs a pile of other workarounds that are not being submitted for mainline inclusion. So the fact that this breaks old hardware is not a problem at this time. Signed-off-by: Olof Johansson <olof@lixom.net> Signed-off-by: Jeff Garzik <jeff@garzik.org>

* pasemi_mac: workaround for erratum 5971Olof Johansson2007-10-10
| | | | | | | | | | | | pasemi_mac: workaround for erratum 5971 Implement workarounds for erratum 5971, where L2 hints aren't considered properly unless the way hint is enabled on the interface. Since L2 isn't setup to dedicate a way to headers, we need to reset the packet count by hand so it won't run out of credits.

* [NET] drivers/net: statistics cleanup #1 -- save memory and shrink codeJeff Garzik2007-10-10
| | | | | | | | | | | | | | | | | We now have struct net_device_stats embedded in struct net_device, and the default ->get_stats() hook does the obvious thing for us. Run through drivers/net/* and remove the driver-local storage of statistics, and driver-local ->get_stats() hook where applicable. This was just the low-hanging fruit in drivers/net; plenty more drivers remain to be updated.

* pasemi_mac: Stop using the pci config space accessors for register read/writesOlof Johansson2007-10-10
| | | | | | | | | | | | | | | Move away from using the pci config access functions for simple register access. Our device has all of the registers in the config space (hey, from the hardware point of view it looks reasonable :-), so we need to somehow get to it. Newer firmwares have it in the device tree such that we can just get it and ioremap it there (in case it ever moves in future products). For now, provide a hardcoded fallback for older firmwares.

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