2015-08-21route: move lwtunnel state to dst_entryJiri Benc17-130/+48
Currently, the lwtunnel state resides in per-protocol data. This is a problem if we encapsulate ipv6 traffic in an ipv4 tunnel (or vice versa). The xmit function of the tunnel does not know whether the packet has been routed to it by ipv4 or ipv6, yet it needs the lwtstate data. Moving the lwtstate data to dst_entry makes such inter-protocol tunneling possible. As a bonus, this brings a nice diffstat.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-08-18 This series contains updates to igb, e100, e1000e and ixgbe. Shota Suzuki provides a fix for a possible overflow in igb_set_interrupt_capability() which leads to an oops. When changing the number of queues by "ethtool -L", set IGB_FLAG_QUEUE_PAIRS in the same manner as when initializing the igb driver. Vasily Averin provides a fix for a missing rtnl_unlock() for when we error out due to not being able to allocate memory for our queues. Stefan Assman provides a couple of fixes for igb/igbvf. First changes the igb driver in probe to simply call igb_enable_sriov() instead of igb_sriov_reinit() since we are starting from scratch. Then in igbvf, fix the driver where it does not clear the buffer_info->dma in all cases after calling dma_unmap_single(), which was found by changing the MTU twice. Richard Cochran implements the periodic output function using the programmable clock outputs available in i210 when possible, falling back to the target time for longer periods. Todd adds support for the Marvell PHY 1512 which is required for i354 devices. Then updates igb to make sure SR-IOV init uses the correct number of queues, since recent changes could result in the PF holding onto all of the queues. Alex Williamson provides a fix in the case where a guest OS does not support hot-unplug, so disable SR-IOV prior to unregister_netdev() to avoid the problem. Jia-Ju Bai provides several patches, first knocks some collecting dust off an old e100 driver to add a check to avoid a null pointer dereference. Then cleans up a possible resource leak by releasing the skb buffer allocated when the e100_xmit_prepare() runs into an issue in the DMA mapping. In igb, add a missing rtnl_unlock() for when we error out due to igb_sriov_reinit() in the igb_init_interrupt_scheme(). Provides a e1000e fix, based on suggestions from Alex Duyck to move head/tail register writing to e1000_configure_tx/rx() to avoid a possible null pointer dereference (similar to igb driver). Lastly, fix a possible memory leak in igb_probe(), where the memory shadow_vfta allocated by kcalloc in igb_sw_init() is not freed. Mark simplifies port-specific macros for ixgbe by eliminating explicit comparisons with 0 and enclose formal parameters in parens to eliminate the risk of an operator precedence issue. ==================== Signed-off-by: David S.

2015-08-19lwtunnel: ip tunnel: fix multiple routes with different encapJiri Benc1-0/+7
Currently, two routes going through the same tunnel interface are considered the same even when they are routed to a different host after encapsulation. This causes all routes added after the first one to have incorrect encapsulation parameters. This is nicely visible by doing: # ip r a 192.168.1.2/32 dev vxlan0 tunnel dst 10.0.0.2 # ip r a 192.168.1.3/32 dev vxlan0 tunnel dst 10.0.0.3 # ip r [...] 192.168.1.2/32 tunnel id 0 src 0.0.0.0 dst 10.0.0.2 [...] 192.168.1.3/32 tunnel id 0 src 0.0.0.0 dst 10.0.0.2 [...] Implement the missing comparison function.

2015-08-19bnx2x: Add vxlan RSS supportRajesh Borundia4-0/+123
Latest FW submission added some vxlan offload capabilities to our device. This patch adds the ability to connect to the vxlan NDOs and configure the UDP port associated with it in the HW. The device would now be capable of performing RSS according to the inner headers of the vxlan packets.

2015-08-19Merge branch 'dsa-multi-swtich'David S. Miller4-23/+71
Andrew Lunn says: ==================== D in DSA patches The D in DSA is distributed, meaning multiple switches can be connected together. Currently no mainline system does this, and so the code is broken. This patchset contains two fixes, and a small helper. With three of more switches, the current device tree binding is not sufficient to express the routing between the switches. The first patch extends the binding, in a backwards compatible way, to allow a link between a switch to describe all the switches accessible over the link, not just the direct neighbor. The third patch fixes the port configuration on newer devices for links connecting switches. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-19dsa: mv88e6xxx: Set DSA mode based on chip abilitiesAndrew Lunn1-5/+8
Older devices only support a single DSA frame format, where as newer devices have two. Take this into account when configuring a DSA port. The port needs to be in plain old DSA mode, since this is a DSA link, where as the newer format can be used for the CPU port. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2015-08-19net: dsa: Allow multi hop routes to be expressedAndrew Lunn2-16/+57
With more than two switches in a hierarchy, it becomes necessary to describe multi-hop routes between switches. The current binding does not allow this, although the older platform_data did. Extend the link property to be a list rather than a single phandle to a remote switch. It is then possible to express that a port should be used to reach more than one switch and the switch maybe more than one hop away.
