2010-12-11bonding: 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.

2010-12-11vxge: 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.

2010-12-11vxge: transmit timeout deadlockJon Mason
Use a workqueue to handle the device reset during a transmit timeout, as there can be a deadlock during bringup.

2010-12-11vxge: 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.

2010-12-10ethtool: 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.

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.

2010-12-10net: optimize INET input path furtherEric Dumazet
Followup of commit b178bb3dfc30 (net: reorder struct sock fields) Optimize INET input path a bit further, by : 1) moving sk_refcnt close to sk_lock. This reduces number of dirtied cache lines by one on 64bit arches (and 64 bytes cache line size). 2) moving inet_daddr & inet_rcv_saddr at the beginning of sk (same cache line than hash / family / bound_dev_if / nulls_node) This reduces number of accessed cache lines in lookups by one, and dont increase size of inet and timewait socks. inet and tw sockets now share same place-holder for these fields. Before patch : offsetof(struct sock, sk_refcnt) = 0x10 offsetof(struct sock, sk_lock) = 0x40 offsetof(struct sock, sk_receive_queue) = 0x60 offsetof(struct inet_sock, inet_daddr) = 0x270 offsetof(struct inet_sock, inet_rcv_saddr) = 0x274 After patch : offsetof(struct sock, sk_refcnt) = 0x44 offsetof(struct sock, sk_lock) = 0x48 offsetof(struct sock, sk_receive_queue) = 0x68 offsetof(struct inet_sock, inet_daddr) = 0x0 offsetof(struct inet_sock, inet_rcv_saddr) = 0x4 compute_score() (udp or tcp) now use a single cache line per ignored item, instead of two.

2010-12-09net: Abstract away all dst_entry metrics accesses.David S. Miller
Use helper functions to hide all direct accesses, especially writes, to dst_entry metrics values. This will allow us to: 1) More easily change how the metrics are stored. 2) Implement COW for metrics. In particular this will help us put metrics into the inetpeer cache if that is what we end up doing. We can make the _metrics member a pointer instead of an array, initially have it point at the read-only metrics in the FIB, and then on the first set grab an inetpeer entry and point the _metrics member there.
