2010-12-10bonding: add the debugfs facility to the bonding driverTaku Izumi
This patch provides the debugfs facility to the bonding driver. The "bonding" directory is created in the debugfs root and directories of each bonding interface (like bond0, bond1...) are created in that. # mount -t debugfs none /sys/kernel/debug # ls /sys/kernel/debug/bonding bond0 bond1 Signed-off-by: Taku Izumi <izumi.taku@jp.fujitsu.com> Signed-off-by: Jay Vosburgh <fubar@us.ibm.com> Signed-off-by: David S.

2010-12-10isdn: return -EFAULT if copy_from_user() failsDan Carpenter
We should be returning -EFAULT here. Mostly this patch is to silence a smatch warning. The upper levels of this driver turn all non-zero return values from isar_load_firmware() into 1. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-12-10vxge: independent interrupt moderationJon Mason
Configure the workload clock register and TIM register for independent interrupt moderation based on the individual vpath utilization instead of common link utilization. This greatly improves latency. Signed-off-by: Jon Mason <jon.mason@exar.com> Signed-off-by: Ram Vepa <ram.vepa@exar.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-12-10vxge: hotplug stallJon Mason
When hot-unplugging a vxge adapter while running, the driver's remove routine prints warning and then stalls the calling thread. This is due to vxge_remove calling vxge_device_unregister to unregister the netdev before calling flush_scheduled_work clear any pending work. Swapping the order of these two functions resolves the issue. Signed-off-by: Jon Mason <jon.mason@exar.com> Signed-off-by: Ram Vepa <ram.vepa@exar.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-12-10vxge: transmit timeout deadlockJon Mason
Use a workqueue to handle the device reset during a transmit timeout, as there can be a deadlock during bringup. Also, set the netif carrier off before the watchdog reset is started to prevent the timeout from reoccurring while still processing the first.

2010-12-10vxge: use pci_request_region()Jon Mason
Only BAR0 is ever accessed, thus making the calls to pci_request_regions overkill. Change calls of pci_request_regions to pci_request_region to reduce the size of the mapped area.

2010-12-10vxge: fix crash of VF when unloading PFJon Mason
Calling pci_disable_sriov when unloading a SR-IOV physical function driver from a host when a guest is using a virtual function from that device can cause a host crash or VM crash. The crash is caused by the virtual config space no longer being present when PF is removed (due to the pci_disable_sriov). This can be avoided by not calling pci_disable_sriov to disable the PCI space when shutting down the PF. Each function in the X3100 operates independently and in this case will operate properly in the absence of the PF. Also, added improved logic in the detection of SR-IOV initialization.

2010-12-10bridge: Use consistent NF_DROP returns in nf_pre_routingHerbert Xu
The nf_pre_routing functions in bridging have collected two distinct ways of returning NF_DROP over the years, inline and via goto. There is no reason for preferring either one. So this patch arbitrarily picks the inline variant and converts the all the gotos. Also removes a redundant comment. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2010-12-10netdev: Use default implementation of ethtool_ops::get_link where possibleBen Hutchings
Various drivers are using implementations of ethtool_ops::get_link that are equivalent to the default ethtool_op_get_link(). Change them to use that instead. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-12-10ethtool: Report link-down while interface is downBen Hutchings
While an interface is down, many implementations of ethtool_ops::get_link, including the default, ethtool_op_get_link(), will report the last link state seen while the interface was up. In general the current physical link state is not available if the interface is down. Define ETHTOOL_GLINK to reflect whether the interface *and* any physical port have a working link, and consistently return 0 when the interface is down.

2010-12-10enic: Use VF mac set by IFLA_VF_MAC in port profile provisioning dataRoopa Prabhu
This patch adds support in enic 802.1Qbh port profile provisioning code to use the mac address set by IFLA_VF_MAC. For now we handle this mac as a special case for a VM mac address sent to us by libvirt. The VM mac address is sent to the switch along with the rest of the port profile provisioning data. This patch also adds calls to register and deregister the mac address during port profile association/deassociation.

2010-12-10pktgen: adding prefetchw() callJunchang Wang
We know for sure pktgen is going to write skb->data right after *_alloc_skb, causing unnecessary cache misses. Idea is to add a prefetchw() call to prefetch the first cache line indicated by skb->data. On systems with Adjacent Cache Line Prefetch, it's probably two cache lines are prefetched. With this patch, pktgen on Intel SR1625 server with two E5530 quad-core processors and a single ixgbe-based NIC went from 8.63Mpps to 9.03Mpps, with 4.6% improvement.
