[dpdk-dev] [PATCH 1/3] eal: fix keep alive header for C++

[Thomas Monjalon <thomas.monjalon@6wind.com>]

When built in a C++ application, the keepalive include fails:

rte_keepalive.h:142:41: error: ‘ALIVE’ was not declared in this scope
  keepcfg->state_flags[rte_lcore_id()] = ALIVE;
                                         ^

Fixes: 75583b0d1efd ("eal: add keep alive monitoring")
