2017-10-11Revert "VPP-1001 - update AF Packet Driver to for modern kernels"Damjan Marion1-59/+7
Issues observed with specific kernel versions, e.g. stock Ubuntu 16.04 kernel. This reverts commit 3eab064e3fadaf2a6a128f167ad04ca0319b4e17. Change-Id: I24241f3b580df749fc686af3a319011ca035fb5e Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-10-04[aarch64] Fixes CLI crashes on dpaa2 platform.Christophe Fontaine1-1/+1
- always use 'va_args' as pointer in all format_* functions - u32 for all 'indent' params as it's declaration was inconsistent Change-Id: Ic5799309a6b104c9b50fec309cba789c8da99e79 Signed-off-by: Christophe Fontaine <christophe.fontaine@enea.com>
2017-10-04VPP-1001 - update AF Packet Driver to for modern kernelsAnton Ivanov1-7/+59
1. Add VNET headers support for checksumming - required to operate correctly on any recent Linux 2. Bypass QDISC on transmit - improves performance by ~ 5%. Enabled only if the macro is detected - apparently not present on archaic distributions. This still does not solve all issues with TSO - it can be fixed only by going to tpacket v3 and dynamic rx ring as well as significant changes in the TX (sendmmsg?).

2017-09-27VLAN support on host(af-packet) interface.Akshaya N1-3/+26
On host interface if a VLAN tagged packet is received, linux kernel removes the VLAN header from packet byte stream and adds metadata in tpacket2_hdr. This patch explicitely checks for the presense of VLAN metadata and adds it in VPP packet. Change-Id: I0ba35c1e98dbc008ce18d032f22f2717d610c1aa Signed-off-by: Akshaya N <akshaya@rtbrick.com>

2017-04-06Use thread local storage for thread indexDamjan Marion1-10/+10
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.

2017-03-20vnet: add device-input threadplacement infraDamjan Marion1-14/+9
This change adds two new debug CLI command: - "show interface placmenet" to display which thread (main or worker) is responsible for processing interface rx queue vpp# show interface placement Thread 0 (vpp_main): node af-packet-input: host-vpp1 queue 0 Thread 1 (vpp_wk_0): node af-packet-input: host-virbr0 queue 0 Thread 2 (vpp_wk_1): node af-packet-input: host-vpp2 queue 0 host-lxcbr0 queue 0 - "set interface placmenet" to assign thread (main or worker) which process specific interface rx queue vpp# set interface placement host-vpp1 queue 0 main Change-Id: Id4dd00cf2b05e10fae2125ac7cb4411b446c5e9c Signed-off-by: Damjan Marion <damarion@cisco.com>
