Subject: eal: allow to override init macros per OS
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=4b3997680ab61636df489299d7980102e00bcf0a;p=dpdk.git

eal: allow to override init macros per OS

baremetal execution environments may have a different
method to enable RTE_INIT instead of using compiler
constructor and/or OS specific linker scheme.
Allow an option to override RTE_INIT* macros using
rte_os.h or appropriate header file.
