2014-06-10bridge: add export of multicast database adjacent to net_devLinus Lüssing
With this new, exported function br_multicast_list_adjacent(net_dev) a list of IPv4/6 addresses is returned. This list contains all multicast addresses sensed by the bridge multicast snooping feature on all bridge ports of the bridge interface of net_dev, excluding addresses from the specified net_device itself. Adding bridge support to the batman-adv multicast optimization requires batman-adv knowing about the existence of bridged-in multicast listeners to be able to reliably serve them with multicast packets.

2014-06-10bridge: adhere to querier election mechanism specified by RFCsLinus Lüssing
MLDv1 (RFC2710 section 6), MLDv2 (RFC3810 section 7.6.2), IGMPv2 (RFC2236 section 3) and IGMPv3 (RFC3376 section 6.6.2) specify that the querier with lowest source address shall become the selected querier. So far the bridge stopped its querier as soon as it heard another querier regardless of its source address. This results in the "wrong" querier potentially becoming the active querier or a potential, unnecessary querying delay. With this patch the bridge memorizes the source address of the currently selected querier and ignores queries from queriers with a higher source address than the currently selected one. This slight optimization is supposed to make it more RFC compliant (but is rather uncritical and therefore probably not necessary to be queued for stable kernels).

2014-06-10bridge: rename struct bridge_mcast_query/querierLinus Lüssing
The current naming of these two structs is very random, in that reversing their naming would not make any semantical difference. This patch tries to make the naming less confusing by giving them a more specific, distinguishable naming. This is also useful for the upcoming patches reintroducing the "struct bridge_mcast_querier" but for storing information about the selected querier (no matter if our own or a foreign querier).

2014-06-10ipip, sit: fix ipv4_{update_pmtu,redirect} callsDmitry Popov
ipv4_{update_pmtu,redirect} were called with tunnel's ifindex (t->dev is a tunnel netdevice). It caused wrong route lookup and failure of pmtu update or redirect. We should use the same ifindex that we use in ip_route_output_* in *tunnel_xmit code. It is t->parms.link . Signed-off-by: Dmitry Popov <ixaphire@qrator.net> Signed-off-by: David S.

2014-06-11drm/nouveau/dp: fix support for dpmsBen Skeggs
SOR_PWR has no effect to power-off DP links, unlike other SOR protocols. Instead, on the source side, we cut power to the lanes after having put the sink into D3. Link training takes care of everything required to bring it back again. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-06-11drm/nouveau/disp/dp: maintain link in response to hpd signalBen Skeggs
This previously worked for the most part due to userspace doing a modeset in response to HPD interrupts. This will allow us to properly handle cases where sync is lost for other reasons, or if userspace isn't caring. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>

2014-06-11drm/nouveau/i2c: introduce locking at a per-port levelBen Skeggs
There's also provisions to allow a pad to be locked with a specific routing, for an indefinite period of time. This will be used in future patches. The G94+ pad driver will now also power-down pads when not required. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
2014-06-11drm/nouveau/i2c: balance port acquire/releaseBen Skeggs
This was a half-finished hack before, just enough to handle the shared aux/i2c pad thing on G94 and up. We got lucky with locking etc up until now, as this was (generally) all protected by the DRM mode_config lock. It's about to become a lot more likely to hit the races.

2014-06-10Merge branch 'cxgb4'David S. Miller
Hariprasad Shenai says: ==================== Adds support for CIQ and other misc. fixes for rdma/cxgb4 This patch series adds support to allocate and use IQs specifically for indirect interrupts, adds fixes to align ISS for iWARP connections & fixes related to tcp snd/rvd window for Chelsio T4/T5 adapters on iw_cxgb4. Also changes Interrupt Holdoff Packet Count threshold of response queues for cxgb4 driver. The patches series is created against 'net-next' tree. And includes patches on cxgb4 and iw_cxgb4 driver. Since this patch-series contains cxgb4 and iw_cxgb4 patches, we would like to request this patch series to get merged via David Miller's 'net-next' tree. We have included all the maintainers of respective drivers. Kindly review the change and let us know in case of any review comments. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
