> Commit b35848bc01f6 ("crypto/ipsec_mb: add multi-process IPC request
> handler") is part of DPDK 22.11 release and it enforces usage of shared
> config and multiprocess mode.
> 
> DPDK is not required to be run with more than one process in general, so
> instead of erroring out, catch the error and proceed with ipsec_mb
> device creation normally.
