Hi,
I can't make my DPDK application on FreeBSD, and i give the following error
       fatal error: rte_kni.h: No such file or directory
       #include <rte_kni.h>
In, ubuntu and debian, I load rte_kni.ko before compilation; However, there
is no such file in FreeBSD version!
my .../dpdk-2.2.0/x86_64-native-bsdapp-gcc/kmod/ directory only contains:
      contigmem.ko    nic_uio.ko
Thanks in advance for your help
