* 6lowpan: revert 'reuse eth_mac_addr()'alex.bluesman.smirnov@gmail.com2012-07-051-2/+14
| | | | | | | | | | | | This reverts the commit cdf49c283e2e105da86ca575ad35b453f5ff24ea which replaces lowpan '.ndo_set_mac_address' method by ethernet's one. Accorind to the IEEE 802.15.4 standard, device has 8-byte length address, so this hook loses the last 2 bytes which may rise a compatibility problems with other IEEE 802.15.4 standard implementations.

* net-next: Add netif_get_num_default_rss_queuesYuval Mintz2012-07-052-0/+14
| | | | | | | | | | | | Most multi-queue networking driver consider the number of online cpus when configuring RSS queues. This patch adds a wrapper to the number of cpus, setting an upper limit on the number of cpus a driver should consider (by default) when allocating resources for his queues.

* net: Do delayed neigh confirmation.David S. Miller2012-07-056-32/+38
| | | | | | | | | | | | | | When a dst_confirm() happens, mark the confirmation as pending in the dst. Then on the next packet out, when we have the neigh in-hand, do the update. This removes the dependency in dst_confirm() of dst's having an attached neigh. While we're here, remove the explicit 'dst' NULL check, all except 2 or 3 call sites ensure it's not NULL. So just fix those cases up. Signed-off-by: David S. Miller <davem@davemloft.net>
* sunrpc: Don't do a dst_confirm() on an input routes.David S. Miller2012-07-051-3/+0
| | | | | | | | | | | | xs_udp_data_ready() is operating on received packets, and tries to do a dst_confirm() on the dst attached to the SKB. This isn't right, dst confirmation is for output routes, not input rights. It's for resetting the timers on the nexthop neighbour entry for the route, indicating that we've got good evidence that we've successfully reached it. Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv4: Don't report neigh uptodate state in rtcache procfs.David S. Miller2012-07-051-10/+2

| | | | | | | | | | | | | | | | | | | | | | | | The "bat_" prefix in the source files implementing the batman-adv sysfs and debugfs interface doesn't have a special meaning and are only used by these files and files that implement the actual B.A.T.M.A.N. path finding algorithm. The prefix is better suited to mark files that are used to implement the main part of the path finding. All other files should not use it and therefore gets renamed.
