(i.e. x86 in ~98% of the cases) This is what x86 uses and it generally helps keep 64-bit code 32-bit clean too.

Add per-device dma_mapping_ops support for CONFIG_X86_64 as POWER architecture does: This enables us to cleanly fix the Calgary IOMMU issue that some devices are not behind the IOMMU (http://lkml.org/lkml/2008/5/8/423). I think that per-device dma_mapping_ops support would be also helpful for KVM people to support PCI passthrough but Andi thinks that this makes it difficult to support the PCI passthrough (see the above thread). So I CC'ed this to KVM camp. Comments are appreciated. A pointer to dma_mapping_ops to struct dev_archdata is added. If the pointer is non NULL, DMA operations in asm/dma-mapping.h use it. If it's NULL, the system-wide dma_ops pointer is used as before. If it's useful for KVM people, I plan to implement a mechanism to register a hook called when a new pci (or dma capable) device is created (it works with hot plugging). It enables IOMMUs to set up an appropriate dma_mapping_ops per device. The major obstacle is that dma_mapping_error doesn't take a pointer to the device unlike other DMA operations. So x86 can't have dma_mapping_ops per device. Note all the POWER IOMMUs use the same dma_mapping_error function so this is not a problem for POWER but x86 IOMMUs use different dma_mapping_error functions. The first patch adds the device argument to dma_mapping_error. The patch is trivial but large since it touches lots of drivers and dma-mapping.h in all the architecture. This patch: dma_mapping_error() doesn't take a pointer to the device unlike other DMA operations. So we can't have dma_mapping_ops per device. Note that POWER already has dma_mapping_ops per device but all the POWER IOMMUs use the same dma_mapping_error function. x86 IOMMUs use device argument.

iph->tot_len is stored in network byte order, so access it using ntohs(). This doesn't have any real world impact on pasemi_mac, since the device only exists as part of a big-endian system-on-chip, but fixing this gets rid of a sparse warning and avoids having a bad example in the tree.

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: Improve RX interrupt mitigation Currently the receive side interrupts will go off on the reception of a packet, NAPI will poll the ring and keep polling as long as there's a decent amount of packets to receive. This is less than optimal, especially for LRO where it's better if we have a more substantial amount of packets to process at once, to get the real LRO benefits. So, set the count threshold to a higher value and use the timeout feature that will give us an interrupt even if not enough packets have come in to set off the count threshold. FIXME: It'd be real nice to have ethtool support for users to tune this at runtime. Signed-off-by: NOlof Johansson <olof@lixom.net> Signed-off-by: NJeff Garzik <jeff@garzik.org>

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: NOlof Johansson <olof@lixom.net> Signed-off-by: NJeff Garzik <jeff@garzik.org>
