[dpdk-dev,v5,04/19] eal: fix wrong strnlen() return value in 32bit icc
Commit Message
The problem is that strnlen() here may return invalid value with 32bit icc.
(actually it returns it’s second parameter,e.g: sysconf(_SC_ARG_MAX)).
It starts to manifest hwen max_len parameter is > 2M and using icc –m32 –O2 (or above).
