[dpdk-dev] [PATCH v2 00/15] support multi-pthread per core

[Cunming Liang]

v2 changes:
  add '<number>-<number>' support for EAL option '--lcores' 

The patch series contain the enhancements of EAL and fixes for libraries
to run multi-pthreads(either EAL or non-EAL thread) per physical core. 
Two major changes list as below:
- Extend the core affinity of each EAL thread to 1:n.
  Each lcore stands for a EAL thread rather than a logical core.
  The change adds new EAL option to allow static lcore to cpuset assginment.
  Then a lcore(EAL thread) affinity to a cpuset, original 1:1 mapping is the special case.
- Fix the libraries to allow running on any non-EAL thread.
  It fix the gaps running libraries in non-EAL thread(dynamic created by user).
  Each fix libraries take care the case of rte_lcore_id() >= RTE_MAX_LCORE.
  
Thanks a million for the comments from Konstantin, Bruce, Mirek and Stephen in RFC review.
