examples/performance-thread: fix build on FreeBSD
This set of sample apps did not compile on FreeBSD due to use of a number of Linux/glibc-specific APIs, or APIs which existed in different headers on FreeBSD. Specifically, the following APIs has problems: * sched_getcpu() is a glibc extension, so use rte_lcore_id() on BSD * pthread_yield() returns int on Linux, but void on FreeBSD, so we have to create two slightly different copies of the function. * the type for managing cpu sets is cpuset_t on FreeBSD rather than cpu_set_t as on Linux, so use rte_cpuset_t from rte_lcore.h. * APIs for managing cpu affinity are in pthread_np.h on FreeBSD, rather than in pthread.h, also fixed by including rte_lcore.h Fixes: 433ba6228f9a ("examples/performance-thread: add pthread_shim app") Fixes: d48415e1fee3 ("examples/performance-thread: add l3fwd-thread app") Cc: stable@dpdk.org Signed-off-by: Bruce Richardson <bruce.richardson@intel.com>
