2017-07-14Introduce l{2,3,4}_hdr_offset fields in the buffer metadataDamjan Marion1-1/+7
To save space in the first cacheline following is changed: - total_length_not_including_first_buffer moved to the 2nd cacheline. This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and VLIB_BUFFER_NEXT_PRESENT are both set. - free_list_index is now stored in 4bits inside flags, which allows up to 16 free lists. In case we need more we can store index in the 2nd cachelin Change-Id: Ic8521350819391af470d31d3fa1013e67ecb7681 Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-05-15[plugins/dpdk] Support for CLIB_HAVE_64 (aarch64)Christophe Fontaine1-0/+13
For platforms which do not support u8x32, such as aarch64, add an alternative implementation of 'dpdk_buffer_init_from_template'. Change-Id: Ia7e8d0a5985fa5925e063ed6e890208c73e39933 Signed-off-by: Christophe Fontaine <christophe.fontaine@enea.com>

2017-04-11dpdk: use common interface placement infraDamjan Marion1-4/+5
This pathch deprecates "show dpdk placement" and "set dpdk placement" CLI commands. Change-Id: I4e052ec3e8b8e6c54b4816e1e689e5b7a24892db Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-04-07MPLS McastNeale Ranns1-1/+1
1 - interface-DPO Used in the Data-plane to change a packet's input interface 2 - MPLS multicast FIB entry Same as a unicast entry but it links to a replicate not a load-balance DPO 3 - Multicast MPLS tunnel Update MPLS tunnels to use a FIB path-list to describe the endpoint[s]. Use the path-list to generate the forwarding chain (DPOs) to link to . 4 - Resolve a path via a local label (of an mLDP LSP) For IP multicast entries to use an LSP in the replication list, we need to decribe the 'resolve-via-label' where the label is that of a multicast LSP. 5 - MPLS disposition path sets RPF-ID For a interface-less LSP (i.e. mLDP not RSVP-TE) at the tail of the LSP we still need to perform an RPF check. An MPLS disposition DPO performs the MPLS pop validation checks and sets the RPF-ID in the packet. 6 - RPF check with per-entry RPF-ID An RPF-ID is used instead of a real interface SW if index in the case the IP traffic arrives from an LSP that does not have an associated interface.

2017-04-06Use thread local storage for thread indexDamjan Marion1-15/+17
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.

2017-03-14Fix packet trace output: dpdk_rx_trace must decode the actual ethertypeDave Barach1-1/+31
As opposed to rubbish (typically) 14 octets past the ethertype. Also fix buffer error code setup in dpdk-input node single loop. Change-Id: Ide7c4097d3bb91e62749ed4e1d69a7b4b90225de Signed-off-by: Dave Barach <dbarach@cisco.com> Signed-off-by: John Lo <loj@cisco.com>
2017-03-08dpdk: dpdk-input optimizations and fixesDamjan Marion1-96/+104
- fix issue caused by assumption that ethertype starts at 0 - intoduce buffer templates to speed-up vlib_buffer_t metadata initialization - avoid check for multiseg buffers inside loop if multiseg is disabled - interleave prefetches to reduce load on L1 cache Change-Id: I3b76e6d3e1e15ed28f01625edb7fbe9f38112e03 Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-03-02Determine pkt type in dpdk-input node using ethertype only (VPP-647)John Lo1-52/+22
Remove reliance on DPDK driver provided mbuf packet type in dpdk-input node as some NIC driver provide misleading information. Now using ethertype from the packet itself to determine packet type for next node. Change-Id: Ie7b514a984f9382c29f1a1e3eb423d68f817c064 Signed-off-by: John Lo <loj@cisco.com>
