This patch anticipates the support for the IOAM insertion inside in-transit packets, by making a difference between input and output in order to determine the right value for its hop-limit (inherited from the IPv6 hop-limit). Input case: happens before ip6_forward, the IPv6 hop-limit is not decremented yet -> decrement the IOAM hop-limit to reflect the new hop inside the trace. Output case: happens after ip6_forward, the IPv6 hop-limit has already been decremented -> keep the same value for the IOAM hop-limit. Signed-off-by:

This patch caches doorbell address directly in struct mlx4_en_tx_ring. This removes the need to bring in cpu caches whole struct mlx4_uar in fast path. Note that mlx4_uar is not guaranteed to be on a local node, because mlx4_bf_alloc() uses a single free list (priv->bf_list) regardless of its node parameter. This kind of change does matter in presence of light/moderate traffic. In high stress, this read-only line would be kept hot in caches. Signed-off-by:

Jakub Kicinski says: ==================== Use netdev->dev_addr write helpers (part 1) Commit 406f42fa ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. This is the first installment of predictably tedious conversion. It tackles: memcpy(netdev->dev_addr, something, ETH_ADDR) and ether_addr_copy(netdev->dev_addr, something) replacing both with eth_hw_addr_set(). The first 7 patches are done entirely by sparse. Next 4 were semi-manual because the sparse conversion resulted in errors. ==================== Signed-off-by:

Vladimir Oltean says: ==================== Egress VLAN modification using VCAP ES0 on Ocelot switches This patch set adds support for modifying a VLAN ID at the egress stage of Ocelot/Felix switch ports. It is useful for replicating a packet on multiple ports, and each egress port sends it using a different VLAN ID. Tested by rewriting the VLAN ID of both (a) packets injected from the CPU port (b) packets received from an external station on a front-facing port Adding a selftest to make sure it doesn't bit-rot, and if it does, that it can be traced back easily. ==================== Signed-off-by: -

For this test we are exercising the VCAP ES0 block's ability to match on a packet with a given VLAN ID, and push an ES0 TAG A with a VID derived from VID_A_VAL plus the classified VLAN. $eth3.200 is the generator port $eth0 is the bridged DUT port that receives $eth1 is the bridged DUT port that forwards and rewrites VID 200 to 300 on egress via VCAP ES0 $eth2 is the port that receives from the DUT port $eth1 Since the egress rewriting happens outside the bridging service, VID 300 does not need to be in the bridge VLAN table of $eth1.

Currently, all packets injected into Ocelot switches are classified to VLAN 0, regardless of whether they are VLAN-tagged or not. This is because the switch only looks at the VLAN TCI from the DSA tag. VLAN 0 is then stripped on egress due to REW_TAG_CFG_TAG_CFG. There are 2 cases really, below is the explanation for ocelot_port_set_native_vlan: - Port is VLAN-aware, we set REW_TAG_CFG_TAG_CFG to 1 (egress-tag all frames except VID 0 and the native VLAN) if a native VLAN exists, or to 3 otherwise (tag all frames, including VID 0). - Port is VLAN-unaware, we set REW_TAG_CFG_TAG_CFG to 0 (port tagging disabled, classified VLAN never appears in the packet). One can already see an inconsistency: when a native VLAN exists, VID 0 is egress-untagged, but when it doesn't, VID 0 is egress-tagged. So when we do this: ip link add br0 type bridge vlan_filtering 1 ip link set swp0 master br0 bridge vlan del dev swp0 vid 1 bridge vlan add dev swp0 vid 1 pvid # but not untagged and we ping through swp0, packets will look like this: MAC > 33:33:00:00:00:02, ethertype 802.1Q (0x8100): vlan 0, p 0, ethertype 802.1Q (0x8100), vlan 1, p 0, ethertype IPv6 (0x86dd), ICMP6, router solicitation, length 16 So VID 1 frames (sent that way by the Linux bridge) are encapsulated in a VID 0 header - the classified VLAN of the packets as far as the hw is concerned. To avoid that, what we really need to do is stop injecting packets using the classified VLAN of 0. This patch strips the VLAN header from the skb payload, if that VLAN exists and if the port is under a VLAN-aware bridge. Then it copies that VLAN header into the DSA injection frame header. A positive side effect is that VCAP ES0 VLAN rewriting rules now work for packets injected from the CPU into a port that's under a VLAN-aware bridge, and we are able to match those packets by the VLAN ID that was sent by the network stack, and not by VLAN ID 0.

The VLAN TCI contains more than the VLAN ID, it also has the VLAN PCP and Drop Eligibility Indicator. If the ocelot driver is going to write the VLAN header inside the DSA tag, it could just as well write the entire TCI. Signed-off-by:

Currently the ocelot driver does support the 'vlan modify' action, but in the ingress chain, and it is offloaded to VCAP IS1. This action changes the classified VLAN before the packet enters the bridging service, and the bridging works with the classified VLAN modified by VCAP IS1. That is good for some use cases, but there are others where the VLAN must be modified at the stage of the egress port, after the packet has exited the bridging service. One example is simulating IEEE 802.1CB active stream identification filters ("active" means that not only the rule matches on a packet flow, but it is also able to change some headers). For example, a stream is replicated on two egress ports, but they must have different VLAN IDs on egress ports A and B. This seems like a task for the VCAP ES0, but that currently only supports pushing the ES0 tag A, which is specified in the rule. Pushing another VLAN header is not what we want, but rather overwriting the existing one. It looks like when we push the ES0 tag A, it is actually possible to not only take the ES0 tag A's value from the rule itself (VID_A_VAL), but derive it from the following formula: ES0_TAG_A = Classified VID + VID_A_VAL Otherwise said, ES0_TAG_A can be used to increment with a given value the VLAN ID that the packet was already classified to, and the packet will have this value as an outer VLAN tag. This new VLAN ID value then gets stripped on egress (or not) according to the value of the native VLAN from the bridging service. While the hardware will happily increment the classified VLAN ID for all packets that match the ES0 rule, in practice this would be rather insane, so we only allow this kind of ES0 action if the ES0 filter contains a VLAN ID too, so as to restrict the matching on a known classified VLAN. If we program VID_A_VAL with the delta between the desired final VLAN (ES0_TAG_A) and the classified VLAN, we obtain the desired behavior. It doesn't look like it is possible with the tc-vlan action to modify the VLAN ID but not the PCP. In hardware it is possible to leave the PCP to the classified value, but we unconditionally program it to overwrite it with the PCP value from the rule. Signed-off-by: -

Split the adminq wait into smaller polling periods in order to watch for broken firmware and not have to wait for the full adminq devcmd_timeout. Generally, adminq commands take fewer than 2 msecs. If the FW is busy they can take longer, but usually still under 100 msecs. We set the polling period to 100 msecs in order to start snooping on FW status when a command is taking longer than usual.
