2011-06-20fec_mpc52xx: enable transmit and receive time stamping.Richard Cochran
This patch enables software (and phy device) time stamping. Software time stamping using the SO_TIMESTAMPING API was tested and found to be working on the LITE5200B board.

2011-06-20net: export the receive time stamping hook for non-NAPI driversRichard Cochran
Ethernet MAC drivers based on phylib (but not using NAPI) can enable hardware time stamping in phy devices by calling netif_rx() conditionally based on a call to skb_defer_rx_timestamp(). This commit exports that function so that drivers calling it may be compiled as modules. Signed-off-by: Richard Cochran <richard.cochran@omicron.at> Signed-off-by: David S.

Remove the myri_sbus driver. Why? * There is no possibility of ethernet mode on this adapter, so it's Myrinet only. * It won't inter-op with modern versions of Myrinet, and thus can only work with legacy adapters. * There are no in-kernel Linux drivers for the PCI version of this adapter, so it only can work on ~15 year old Sun hardware.

Using throw_uevent() is now possible to trigger uevent signal that can be recognised in userspace. Uevents will be triggered through the /devices/virtual/net/{MESH_IFACE} kobject. A triggered uevent has three properties: - type: the event class. Who generates the event (only 'gw' is currently defined). Corresponds to the BATTYPE uevent variable. - action: the associated action with the event ('add'/'change'/'del' are currently defined). Corresponds to the BATACTION uevent variable. - data: any useful data for the userspace. Corresponds to the BATDATA uevent variable.

2011-06-20batman-adv: improved roaming mechanismAntonio Quartulli
With the current client announcement implementation, in case of roaming, an update is triggered on the new AP serving the client. At that point the new information is spread around by means of the OGM broadcasting mechanism. Until this operations is not executed, no node is able to correctly route traffic towards the client. This obviously causes packet drops and introduces a delay in the time needed by the client to recover its connections. A new packet type called ROAMING_ADVERTISEMENT is added to account this issue. This message is sent in case of roaming from the new AP serving the client to the old one and will contain the client MAC address. In this way an out-of-OGM update is immediately committed, so that the old node can update its global translation table. Traffic reaching this node will then be redirected to the correct destination utilising the fresher information. Thus reducing the packet drops and the connection recovery delay.

2011-06-20batman-adv: improved client announcement mechanismAntonio Quartulli
The client announcement mechanism informs every mesh node in the network of any connected non-mesh client, in order to find the path towards that client from any given point in the mesh. The old implementation was based on the simple idea of appending a data buffer to each OGM containing all the client MAC addresses the node is serving. All other nodes can populate their global translation tables (table which links client MAC addresses to node addresses) using this MAC address buffer and linking it to the node's address contained in the OGM. A node that wants to contact a client has to lookup the node the client is connected to and its address in the global translation table. It is easy to understand that this implementation suffers from several issues: - big overhead (each and every OGM contains the entire list of connected clients) - high latencies for client route updates due to long OGM trip time and OGM losses The new implementation addresses these issues by appending client changes (new client joined or a client left) to the OGM instead of filling it with all the client addresses each time. In this way nodes can modify their global tables by means of "updates", thus reducing the overhead within the OGMs. To keep the entire network in sync each node maintains a translation table version number (ttvn) and a translation table checksum. These values are spread with the OGM to allow all the network participants to determine whether or not they need to update their translation table information. When a translation table lookup is performed in order to send a packet to a client attached to another node, the destination's ttvn is added to the payload packet. Forwarding nodes can compare the packet's ttvn with their destination's ttvn (this node could have a fresher information than the source) and re-route the packet if necessary. This greatly reduces the packet loss of clients roaming from one AP to the next.

2011-06-19drm/radeon/kms/atom: fix duallink on some early DCE3.2 cardsAlex Deucher
Certain revisions of the vbios on DCE3.2 cards have a bug in the transmitter control table which prevents duallink from being enabled properly on some cards. The action switch statement jumps to the wrong offset for the OUTPUT_ENABLE action. The fix is to use the ENABLE action rather than the OUTPUT_ENABLE action on the affected cards. In fixed version of the vbios, both actions jump to the same offset, so the change should be safe.
