Subject: eal: move thread affinity functions to new file
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=d136fae5604e8a5e638cc5c9f415a5c636f280c8

eal: move thread affinity functions to new file

Move the definition of the functions
rte_thread_set_affinity and rte_thread_get_affinity
to new file, rte_thread.h

The file will implement generic threading functionality
and will only host threading functions which do not reference
pthread API.
