2016-06-17VNET: Initialization support for NXP DPAA2 poll mode driverSachin3-1/+13
- NXP proposed a poll mode driver "rte_dpaa2_dpni" in DPDK upstream. - When using external DPDK with the given dpaa2 driver, VPP needs modification to initialize the PMD and to understand the DPAA2 N/W interfaces.

2016-06-16VPP-19: Split the lookup.h IP_LOOKUP_NEXT enum.Ole Troan11-339/+50
IP4 and IP6 nodes currently shares the adj->lookup_next_index. That has some issues, e.g. that one has to add non-functional nodes like ip4-hop-by-hop and that anyone dynamically adding nodes to any of the IP4/IP6 lookup nodes must ensure they add themselves to all relevant nodes to ensure next index consistency. This patch splits the IP_LOOKUP_NEXT into separate enums for IP4 and IP6 with a common part for next-nodes used by both. It sets up other IP nodes as siblings to avoid inconsistencies. This allows IP4 and IP6 lookup next nodes to evolve independently. The adj->lookup_next_index is still shared, assuming that an IP4 adjacency isn't used by an IP6 graph node.

2016-06-14Fix double-enqueued packet in interface-output dual-loop, fixes VPP-116Damjan Marion3-29/+47
When speculative enqueue fails and a buffer needs to be moved to a new node queue the original buffer is not correctly removed from the original queue so buffer get send for transmit and encryption at the same time. This issue will only be hit with the double loop so low throughput traffic like pings will not hit the issue. This code path is also only hit when the feature flag is enabled so will not be hit by normal traffic Patch also reorgnizes code to reduce number of branches in the interface output node loop.

Previous patch was printing wrong data since rewrite node traces an ethernet packet while other ip nodes trace an IP packet.

2016-06-09VPP-117: Add trace to ip4 and ip6 lookup nodesPierre Pfister4-19/+84
The absence of trace in ip lookup nodes is misleading to many people. This patch adds ip lookup tracing and therefore contribute to worldwide happiness. In addition, this patch makes sure sw_if_index[VLIB_TX] is considered when tracing the fib_index value. In ip4/6-rewrite, the value corresponds to the tx interface index. The formatting function is therefore modified to take that case into account. Change-Id: I5915f0446a15c45e391eedfdfcedd9057aa6a237 Signed-off-by: Pierre Pfister <ppfister@cisco.com>

Remove usage of dummy encap string for output from BD to a tunnel which has been deleted. Instead, use a node l2-outpt-del-tunnel so that if there are stale entries in the L2FIB for any deleted tunnel sw_if_index, l2-output will send packets using this entry to the l2-output-tunnel-del node which just setup the proper drop reason before sending packets to the error-drop node to drop the packet.

The add_del function was not properly checking if a tunnel already existed; instead it was checking if the given tunnel name existed. If no tunnel name was given it flat out refused to add a tunnel even though that is optional. Cleanup the add/del parameter validation to "do what I expect" it to do: When adding a tunnel: - If a "name" is given, it must not exist. - The "key" is always checked, and must not exist. When deleting a tunnel: - If the "name" is given, and it exists, then use it. - If the "name" is not given, use the "key". - If the "name" and the "key" are given, then both must point to the same thing.
