[ovs-discuss] ovs-dpdk cannot add a dpdk mellanox port

[Avi Cohen (A)]

Olga
i'm familiar with the procedure. I can build dpdk 17.11 but has this compilation error in 17.08
Here https://community.mellanox.com/thread/3545  the answer to the same error  is to install another OFED - when I install this OFED, it breaks the build of 17.11 and 17.08
Best Regards
Avi
