2019-02-19tap gso: experimental supportAndrew Yourtchenko1-0/+15
This commit adds a "gso" parameter to existing "create tap..." CLI, and a "no-gso" parameter for the compatibility with the future, when/if defaults change. It makes use of the lowest bit of the "tap_flags" field in the API call in order to allow creation of GSO interfaces via API as well. It does the necessary syscalls to enable the GSO and checksum offload support on the kernel side and sets two flags on the interface: virtio-specific virtio_if_t.gso_enabled, and vnet_hw_interface_t.flags & VNET_HW_INTERFACE_FLAG_SUPPORTS_GSO. The first one, if enabled, triggers the marking of the GSO-encapsulated packets on ingress with VNET_BUFFER_F_GSO flag, and setting vnet_buffer2(b)->gso_size to the desired L4 payload size. VNET_HW_INTERFACE_FLAG_SUPPORTS_GSO determines the egress packet processing in interface-output for such packets: When the flag is set, they are sent out almost as usual (just taking care to set the vnet header for virtio). When the flag is not enabled (the case for most interfaces), the egress path performs the re-segmentation such that the L4 payload of the transmitted packets equals gso_size. The operations in the datapath are enabled only when there is at least one GSO-compatible interface in the system - this is done by tracking the count in interface_main.gso_interface_count. This way the impact of conditional checks for the setups that do not use GSO is minimized. "show tap" CLI shows the state of the GSO flag on the interface, and the total count of GSO-enabled interfaces (which is used to enable the GSO-related processing in the packet path). This commit lacks IPv6 extension header traversal support of any kind - the L4 payload is assumed to follow the IPv6 header. Also it performs the offloads only for TCP (TSO - TCP segmentation offload). The UDP fragmentation offload (UFO) is not part of it. For debug purposes it also adds the debug CLI: "set tap gso {<interface> | sw_if_index <sw_idx>} <enable|disable>" Change-Id: Ifd562db89adcc2208094b3d1032cee8c307aaef9 Signed-off-by: Andrew Yourtchenko <ayourtch@gmail.com>

2018-04-13bond: ping fails between l2 BD [VPP-1238]Steven1-0/+8
In dpdk based bonding, when the bond interface is configured for l2, it automatically sets the bond interface to promiscuous mode and sets rx redirect to ethernet-input. This allows traffic to be bridged to non compute node facing interface when it is received from the compute node interface. For native vpp bonding, we need to do similar things. When the bond interface is configured for l2, we set the slave interfaces to promiscuous mode and set rx redirect to ethernet-input because dpdk does not know anything about the bond interface. Likewise, when a new interface is enslaved, we also need to do the same thing if the bond interface has already been configured for l2.

2018-01-24Improve tunnel interface creation performanceJohn Lo1-0/+4
Modify interface creation to allow creation of tunnel interfaces without dedicated per tunnel output and tx nodes which are not used for most tunnel types. Also changed interface-output node function vnet_per_buffer_interface_output() so it does not rely on hw_if_index as the next node index which is not flexible nor efficient for large scale tunnel interfaces. The improvenemts are done for VXLAN, VXLAN-GPE, GENEVE and GTPU tunnels. GRE tunnel is still using per tunnel output nodes which will be changed in a separate patch with other GRE enhencements.

2017-05-10device: Add callback for set interface rx-modeSteven1-9/+17
- When the interface rx-mode is changed via CLI, the corresponding device may want to know about it and to reset the driver. This patch is to add the callback. - In the function vnet_hw_interface_set_rx_mode, it appears it is missing a line hw->rx_mode_by_queue[queue_id] = mode because the function is checking if the new mode is the same as hw->rx_mode_by_queue which is initialized to POLLING. So if the function is called to change the mode to interrupt, it just returns without doing anything. This is the check that I am talking about in the same function. if (hw->rx_mode_by_queue[queue_id] == mode) return 0; Change-Id: Iaca2651c43e0ae3fda6fd8dc128e247b0851cc65 Signed-off-by: Steven <sluong@cisco.com>
