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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

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:

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:

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. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

If br_multicast_new_group returns NULL, we would return 0 (no error) to the caller of br_multicast_add_group, which is not what we want. Instead br_multicast_new_group should return ERR_PTR(-ENOMEM) in this case. Also propagate the error number returned by br_mdb_rehash properly. Signed-off-by:

Make the LSO code work on BE platforms: parsing_data field of a parsing BD (PBD) for 57712 was improperly composed which made FW read wrong values for TCP header's length and offset and, as a result, the corresponding PCI device was performing bad DMA reads triggering EEH. Signed-off-by:

__load_pointer() checks data we fetch from skb is included in head portion, but assumes we fetch one byte, instead of up to four. This wont crash because we have extra bytes (struct skb_shared_info) after head, but this can read uninitialized bytes. Fix this using size of the data (1, 2, 4 bytes) in the test. Signed-off-by:

The current jhash.h implements the lookup2() hash function by Bob Jenkins. However, lookup2() is outdated as Bob wrote a new hash function called lookup3(). The patch replaces the lookup2() implementation of the 'jhash*' functions with that of lookup3(). You can read a longer comparison of the two and other hash functions at http://burtleburtle.net/bob/hash/doobs.html. Signed-off-by:

Followup of commit b178bb3d (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.

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.
