2012-07-056lowpan: revert 'reuse eth_mac_addr()'alex.bluesman.smirnov@gmail.com
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.

2012-07-05net-next: Add netif_get_num_default_rss_queuesYuval Mintz
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.

2012-07-05net: Add optional SKB arg to dst_ops->neigh_lookup().David S. Miller

2012-07-05net: Do delayed neigh confirmation.David S. Miller
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>
2012-07-05sunrpc: Don't do a dst_confirm() on an input routes.David S. Miller
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>
2012-07-05ipv4: Don't report neigh uptodate state in rtcache procfs.David S. Miller

This patch generalizes nf_ct_l4proto_net by splitting it into chunks and moving the corresponding protocol part to where it really belongs to.

2012-07-04cfg80211: fix locking regression in monitor channel trackingJohannes Berg
Michal's monitor channel tracking introduce a locking problem as it locked the rdev lock inside the netdev notifier which isn't allowed as we might already hold it if we get there by removing an interface that is up. Fix this by relying only on the RTNL to protect the interface counters, the RTNL is always held in these code paths anyway. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Fix from Claudiu Manoil. 10) Missing module.h include in davinci_cpdma.c, from Daniel Mack. 11) Need dummy handler for IPSET_CMD_NONE otherwise we crash in ipset if we get this via nfnetlink, fix from Tomasz Bursztyka. 12) Missing RCU unlock in nfnetlink error path, also from Tomasz. 13) Fix divide by zero in igbvf when the user tries to set an RX coalescing value of 0 usecs, from Mitch A Williams. 14) We can process SCTP sacks for the wrong transport, oops. Fix from Neil Horman. 15) Remove hw IP payload checksumming from e1000e driver. This has zery value in our stack, and turning it on creates a very unintuitive restriction for users when using jumbo MTUs. Specifically, when IP payload checksums are on you cannot use both receive hashing offload and jumbo MTU.

2012-07-03mac80211: add TX prepare APIJohannes Berg
Some drivers require setup before being able to send management frames in managed mode, in particular in multi-channel cases. Introduce API to allow the drivers to do such setup while being able to sleep waiting for the setup to finish in the device. This isn't possible inside the TX call since that can't sleep. A future patch may also restructure the TX retry to wait for the driver to report the frame status, as suggested by Arik in http://mid.gmane.org/CA+XVXffKSEL6ZQPQ98x-zO-NL2=TNF1uN==mprRyUmAaRn254g@mail.gmail.com Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-07-03mac80211: reduce IEEE80211_TX_MAX_RATESThomas Huehn
IEEE80211_TX_MAX_RATES can be reduced from 5 to 4 as there is no current hardware supporting a rate chain with 5 multi rate stages (mrr), so 4 mrr stages are sufficient.

2012-07-01batman-adv: Remove bat_ prefix from bat_{debugfs, sysfs}.{c, h}Sven Eckelmann
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.
