Hi Dmitry,

We meet an issue based on this patch that mempool_autotest execute failed on FreeBSD13.0, bug id is https://bugs.dpdk.org/show_bug.cgi?id=863, could you pls have a look?
Reproduce steps:
2.lanch app
# ./x86_64-native-bsdapp-gcc/app/test/dpdk-test  -n 4 -c f
3. execute dpdk command 
# mempool_autotest
common_pool_count=1598
no statistics available
EAL: Test assert test_mempool_flag_non_io_unset_when_populated_with_valid_iova line 781 failed: Cannot get IOVA
test failed at test_mempool():1030
Test Failed
