Subject: eal: fix config file path when checking process
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=641566b38be46069c796c6e1ce2a89f3df2c2591

eal: fix config file path when checking process

When primary process is booted with --file-prefix option, the API,
rte_eal_primary_proc_alive(), uses a wrong config file path to
check if primary process is alive.

Fix it by calling helper function to get config file path.
