2013-09-03net: neighbour: Remove CONFIG_ARPDTim Gardner4-22/+0
This config option is superfluous in that it only guards a call to neigh_app_ns(). Enabling CONFIG_ARPD by default has no change in behavior. There will now be call to __neigh_notify() for each ARP resolution, which has no impact unless there is a user space daemon waiting to receive the notification, i.e., the case for which CONFIG_ARPD was designed anyways.

2013-09-03virtio-net: Set RXCSUM feature if GUEST_CSUM is availableThomas Huth1-0/+2
If the VIRTIO_NET_F_GUEST_CSUM virtio feature is available, the guest does not have to calculate the checksums on all received packets. This is pretty much the same feature as RX checksum offloading on real network cards, so the virtio-net driver should report this by setting the NETIF_F_RXCSUM flag. When the user now runs "ethtool -k", he or she can see whether the virtio-net interface has to calculate RX checksums or not.

2013-09-03Merge branch 'addr_assign_type'David S. Miller12-11/+26
Bjørn Mork says: ==================== net: set addr_assign_type when inheriting a dev_addr Copying the dev_addr from a parent device is an operation common to a number of drivers. The addr_assign_type should be updated accordingly, either by reusing the value from the source device or explicitly indicating that the address is stolen by setting addr_assign_type to NET_ADDR_STOLEN. This patch set adds a helper copying both the dev_addr and the addr_assign_type, and use this helper in drivers which don't currently set the addr_assign_type. Using NET_ADDR_STOLEN might be more appropriate in some of these cases. Please let me know, and I'll update the patch accordingly. Changes in v2: - assuming addr_len == ETH_ALEN to allow optimized memcpy - dropped the vt6656 patch due to addr_len being unset in that driver ==================== Signed-off-by: David S.

2013-08-31qdisc: allow setting default queuing disciplinestephen hemminger8-8/+112
By default, the pfifo_fast queue discipline has been used by default for all devices. But we have better choices now. This patch allow setting the default queueing discipline with sysctl. This allows easy use of better queueing disciplines on all devices without having to use tc qdisc scripts. It is intended to allow an easy path for distributions to make fq_codel or sfq the default qdisc. This patch also makes pfifo_fast more of a first class qdisc, since it is now possible to manually override the default and explicitly use pfifo_fast. The behavior for systems who do not use the sysctl is unchanged, they still get pfifo_fast Also removes leftover random # in sysctl net core.
