Subject: [PATCH] examples/qos_sched: fix build for less lcores
[ upstream commit e481ebfd622c23a1d854cb4655a3534d68d322af ]
APP_MAX_LCORES is hardcoded as 64.
This will cause build err when RTE_MAX_LCORE is less then 64.
"args.c:127:22: error: iteration 8 invokes undefined behavior
[-Werror=aggressive-loop-optimizations]
if (cfg->lcore_role[i] == ROLE_RTE)
~~~~~~~~~~~~~~~^~~
args.c:126:2: note: within this loop
for (i = 0; i < APP_MAX_LCORE; i++) {"
