[dpdk-dev] [PATCH v7 0/9] enable lpm, acl and other missing libraries in ppc64le

[Gowrishankar <gowrishankar.m@linux.vnet.ibm.com>]

From: Gowrishankar Muthukrishnan <gowrishankar.m@linux.vnet.ibm.com>

This patchset enables LPM, ACL and other few missing libs in ppc64le and also
address few patches in related examples (ip_pipeline and l3fwd).

Test report:
1. LPM and ACL unit tests passed.
   Steps:
   compile test app and run (with any needed params)
   lpm_autotest
   acl_autotest
   table_autotest
     test_table_lpm_combined fails same as in intel in current master.

2. Example ip_pipeline application verified for port forwarding.
   compile examples/ip_pipeline (adjust app_init_core_map
     param for ht to 1 in case of ppc64le in SMT=off mode).
   modify config/l3fwd.cfg as per enabled PMD ports.
   run ip_pipeline with config file option and check packets fwd.

v7 changes:
- removed enforcing cache alignment for table hash structs and
  instead check only for multiples of 64 bytes.

v6 changes:
- added cache alignment fix for rte hash table structs.

v5 changes:
- no change in lpm lib enablement
- no change in acl lib enablement
- config file changes individually for sched,table,port,pipeline
  lib enablement
- ip_pipeline patch description and changes flagged only for ppc64le.
   app_init_core_map changes removed (due to bug found and under 
   investigation only on ppc64le/smt=off case).

v4 changes:
- fix transition4 in acl_run_altivec.h for gcc strict-aliasing error.
  Thanks to Chao Zhu for bringing up.

v3 changes:
- rebase over master to fix conflict in examples/l3fwd/l3fwd_em.c

v2 changes:
- enabling libs in config included as part of lib changes itself.

Gowrishankar Muthukrishnan (9):
  lpm: add altivec intrinsics for dpdk lpm on ppc_64
  acl: add altivec intrinsics for dpdk acl on ppc_64
  l3fwd: add altivec support for em_hash_key
  table: enable table library for ppc64le
  sched: enable sched library for ppc64le
  port: enable port library for ppc64le
  pipeline: enable pipeline library for ppc64le
  ip_pipeline: fix lcore mapping for varying SMT threads as in ppc64
  table: fix verification on hash bucket header alignment
