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.

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: NDavid S. Miller <davem@davemloft.net>

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: NAndrew Lunn <andrew@lunn.ch> Signed-off-by: NDavid S.

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.

Phil Sutter says: ==================== net: Convert drivers to IFF_NO_QUEUE and cleanup afterwards This series converts in-tree users away from the old and deprecated 'tx_queue_len = 0' idiom, adds a warning to notify out-of-tree driver maintainers that there is need for action on their behalf and finally drops any workarounds in scheduling algorithm implementations. ==================== Signed-off-by: NDavid S.

Those were all workarounds for the formerly double meaning of tx_queue_len, which broke scheduling algorithms if untreated. Now that all in-tree drivers have been converted away from setting tx_queue_len = 0, it should be safe to drop these workarounds for categorically broken setups.

Due to the introduction of IFF_NO_QUEUE, there is a better way for drivers to indicate that no qdisc should be attached by default. Though, the old convention can't be dropped since ignoring that setting would break drivers still using it. Instead, add a warning so out-of-tree driver maintainers get a chance to adjust their code before we finally get rid of any special handling of tx_queue_len == 0.

Tom Herbert says: ==================== net: Identifier Locator Addressing - Part I This patch set provides rudimentary support for Identifier Locator Addressing or ILA. The basic concept of ILA is that we split an IPv6 address into a 64 bit locator and 64 bit identifier. The identifier is the identity of an entity in communication ("who"), and the locator expresses the location of the entity ("where"). Applications use externally visible address that contains the identifier. When a packet is actually sent, a translation is done that overwrites the first 64 bits of the address with a locator. The packet can then be forwarded over the network to the host where the addressed entity is located. At the receiver, the reverse translation is done so the that the application sees the original, untranslated address. Presumably an external control plane will provide identifier->locator mappings. v2: - Fix compilation erros when LWT not configured - Consolidate ILA into a single ila.c v3: - Change pseudohdr argument od inet_proto_csum_replace functions to be a bool v4: - In ila_build_state check locator being in netlink params before allocating tunnel state The data path for ILA is a simple NAT translation that only operates on the upper 64 bits of a destination address in IPv6 packets. The basic process is: 1) Lookup 64 bit identifier (lower 64 bits of destination) 2) If a match is found a) Overwrite locator (upper 64 bits of destination) with the new locator b) Adjust any checksum that has destination address included in pseudo header 3) Send or receive packet ILA is a means to implement tunnels or network virtualization without encapsulation. Since there is no encapsulation involved, we assume that stateless support in the network for IPv6 (e.g. RSS, ECMP, TSO, etc.) just works. Also, since we're minimally changing the packet many of the worries about encapsulation (MTU, checksum, fragmentation) are not relevant. The downside is that, ILA is not extensible like other encapsulations (GUE for instance) so it might not be appropriate for all use cases. Also, this only makes sense to do in IPv6! A key aspect of ILA is performance. The intent is that ILA would be used in data centers in virtualizing tasks or jobs. In the fullest incarnation all intra data center communications might be targeted to virtual ILA addresses. This is basically adding a new virtualization capability to the existing services in a datacenter, so there is a strong expectation is that this does not degrade performance for existing applications. Performance seems to be dependent on how ILA is hooked into kernel. ILA can be implemented under some different models: - Mechanically it is a form a stateless DNAT - It can be thought of as a type of (source) routing - As a functional replacement of encapsulation In this patch set we hook into the data path using Light Weight Tunnels (LWT) infrastructure. As part of that, we add support in LWT to redirect dst input. iproute will be modified to take a new ila encap type. ILA can be configured like: ip route add 3333:0:0:1:5555:0:2:0/128 \ encap ila 2001:0:0:2 via 2401:db00:20:911a:face:0:27:0 ip -6 addr add 3333:0:0:1:5555:0:1:0/128 dev eth0 ip route add table local local 2001:0:0:1:5555:0:1:0/128 encap ila 3333:0:0:1 dev lo So sending to destination 3333:0:0:1:5555:0:2:0 will have destination of 2001:0:0:2:5555:0:2:0 on the wire. Performance results are below. With ILA we see about a 10% drop in pps compared to non-ILA. Much of this drop can be attributed to the loss of early demux on input (translation occurs after it is attempted). We will address this in the next patch set. Also, IPvlan input path does not work with ILA since the routing is bypassed-- this will be addressed in a future patch.

Adding new module name ila. This implements ILA translation. Light weight tunnel redirection is used to perform the translation in the data path. This is configured by the "ip -6 route" command using the "encap ila <locator>" option, where <locator> is the value to set in destination locator of the packet. e.g. ip -6 route add 3333:0:0:1:5555:0:1:0/128 \ encap ila 2001:0:0:1 via 2401:db00:20:911a:face:0:25:0 Sets a route where 3333:0:0:1 will be overwritten by 2001:0:0:1 on output.
