ibv_fork_init is part of libibverbs library (RDMA, Inifiband), that is always needed with Mellanox NICs even if Infiniband is not used. Libverbs is installed on my environment, but for some reason the VPP DPDK plugin does not seem to know about it... Maybe a link is missing somewhere?
Is there any VPP MLX PMD documentation available (found some but it's outdated)? Are the Mellanox NICs tested on a regular basis ? I just want to know if I did something wrong or whether there might be an actual issue here.

All bets are off since the dpdk plugin didn't load correctly. You'll need to track down ibv_fork_init(...)... Thanks...
