2016-10-11vppinfra: use crc32q instruction instead of xxhash in bihash_8_8Damjan Marion1-0/+3
xxhash calculation takes 10 clock cycles on Haswell so it makes sense to use crc32q insutrction when available. Change-Id: Iab5e7d9c8ec0125626bbcd067e5dc30574c8febc Signed-off-by: Damjan Marion <damarion@cisco.com>

2016-08-09VPP-189 Fix Coverity warningsDave Barach1-3/+0
Remove a bunch of historical SMP code that we're not using; clean up coverity warnings as a side-effect. Change-Id: Ic80d2f87c7fd4e654078cac23ad5ec287a1d7ffe Signed-off-by: Dave Barach <dave@barachs.net>

2016-06-17Dynamically compute ip feature subgraph orderDave Barach1-1/+8
This change-set enables plugins to add themselves to the ip4/ip6 feature subgraphs without having to modify core vpp engine code at all. Add VNET_IP4/IP6_UNICAST/MULTICAST_FEATURE_INIT macros which express the required ordering constraints, and off you go. Along the way, added an implementation of Warshall's algorithm to vppinfra; to compute the positive transitive closure of a relation. In this case, the relation is "feature A runs before feature B." With that in hand, ip_feature_init_cast(...) computes a partial order across the set of configured feature subgraph nodes. In unit-testing, we discovered VPP-145 - ip4/6 inacl wiped out vnet_buffer(b)->ip>current_config_index, which exists in main. So, we fixed that by moving b->trace_index, adding b->current_config_index, and removing the ip opaque union current_config_index.
