2018-06-11MTU: Software interface / Per-protocol MTU supportOle Troan1-10/+5
This patch separates setting of hardware interfaec and software interface MTU. Software MTU is L2 payload MTU (i.e. not including L2 header). Per-protocol MTU for IPv4, IPv6 and MPLS can also be set. Currently only IP4, IP6 are enabled in adjacency / rewrite code. Documentation in src/vnet/MTU.md Change-Id: Iee2fd6f0bbc8210748dd8e073ab9fab87d323690 Signed-off-by: Ole Troan <ot@cisco.com>

2018-05-31dpdk: Decoupling the meaning of xd->device_index in dpdk_pluginRui Cai1-13/+24
Prior to the change, dpdk plugin assumes xd->device_index is used both as index for internal dpdk_main->devices array and DPDK port index to call into DPDK APIs. However, when running on top of Failsafe PMDs, DPDK port index range may no longer be contiguous (as noted: http://dpdk.org/ml/archives/dev/2018-March/092375.html for related changes in DPDK). Because this, dpdk plugin can no longer iterate through all available DPDK ports with a for 0->rte_eth_dev_count() loop and the assumption of device_index no longer holds. This is part of initial effort to enable vpp running over dpdk on failsafe PMD in Microsoft Azure(3/4).

2018-05-29dpdk: Add PMD type for Cavium LiquidIO II CN23XXchuhong yao1-0/+7
1、Adding PMD type for support Cavium LiquidIO II CN23XX NIC; 2、Our company is using VPP + DPDK +Cavium LiquidIO II CN23XX NIC, Unfortunately, the latest VPP code does not support Cavium LiquidIO II CN23XX pci. So I increased the PMD type to support LiquidIO NIC, and can run normally, we most subsequent projects are based on VPP + DPDK + Cavium LiquidIO II CN23XX NIC model, so I hope VPP team can adopt this requirement, thanks a lot.

2018-05-16dpdk: fix rte_eth_dev_set_mtu callsites to use same mtu valueRui Cai1-1/+1
During dpdk_lib_init, it calculates MRU and MTU and later calls rte_eth_dev_set_mtu with calculated MTU value. However, dpdk_device_setup calls rte_eth_dev_set_mtu with hi->max_packet_bytes, which is set to be MRU value in dpdk_lib_init earlier. Most of the time, MRU != MTU in dpdk_lib_init and it looks like hi->max_packet_bytes is treated as MTU in other parts of vpp codebase. Therefore, dpdk_lib_init should be consistent and use MTU instead of MRU for hi->max_packet_bytes. Change-Id: I23ff2a6cd45d6bc819b6f64d5f0fc0490b8a44de Signed-off-by: Rui Cai <rucai@microsoft.com>
2018-05-11dpdk: fix Unknown interface with Mellanox NICSteve Shin1-1/+1

Calling rte_eth_link_get before getting dev_info will ensure the link state is up-to-date. Change-Id: I83a59654778eb4bf0c65a4a4e225a326227b9641 Signed-off-by: Steve Shin <jonshin@cisco.com>

2018-02-19dpdk: Fix MTU calc for NICs that support mtu<9216Nitin Saxena1-34/+66
Problem: rte_eth_dev_set_mtu() returns with failure from ThunderX NICVF DPDK PMD driver which supports MTU less than ETHERNET_MAX_PACKET_BYTES. rte_eth_dev_set_mtu() being called twice from dpdk_lib_init(): one via dpdk_device_setup() and second in dpdk_lib_init() itself. Currently dpdk_lib_init() passes vnet_hardware_interface->max_packet_bytes as an argument to rte_eth_dev_set_mtu() without consulting dev_info.max_rx_pktlen. NICs like i4oe, ixgbe can support MTU much greater than 9216 hence its not a problem for those NICS. Fix: This patch calculates dpdk_device->port_conf.rxmode.max_rx_pkt_len, vnet_hardware_interface->max_packet_bytes and MTU by consulting dev_info.max_rx_pktlen.

2017-10-24Add extern to *_main global variable declarations in header files.Dave Wallace1-0/+1
- Global variables declared in header files without the use of the 'extern' keword will result in multiple instances of the variable to be created by the compiler -- one for each different source file in which the the header file is included. This results in wasted memory allocated in the BSS segments as well as potentially introducing bugs in the application.

2017-10-04dpdk: use vpp physmem allocator for dpdk buffersDamjan Marion1-44/+78
This allows us to have single contignuous allocation for DPDK buffers with single mmap FD, so buffer memory can be easily shared with diffrent process. As a consequence dpdk socket-mem is no longer in charge for allocating buffer memory, but still we need some space allocated for dpdk structures so default socket-mem is reduced form 256 to 64 MB. For a default of 16K buffers per numa node, physmem allocation is now 40MB, so basically this change reduces footprint from 256MB per socket to 48 (64 + 40).
