[dpdk-dev] [PATCH v3 1/1] net/ionic: use standard stdbool.h

[Sunil Kumar Kori]

Any DPDK public header file which includes stdbool.h may conflict with
local definition of bool, if any, which further results in compilation
error. To avoid, used standard stdbool.h instead of defining bool
internally.

I observed this issue during a development where I included rte_uuid.h
into rte_ethdev.h. As rte_ethdev.h is included to PMD driver, it started
throwing error as given below:
