Applied to dpdk-next-net/main, thanks.

I've a number of concerns:
  * conditional compilation IDPF_RX_PTYPE_OFFLOAD in [PATCH v15 17/18] 
net/idpf: add AVX512 data path for single queue model
  * the same prefix used for functions in common/idpf/base and net/idpf 
drivers
  * common/idpf/base uses own defines for negative errno (defined as a 
number with corresponding errno in a comment). Strictly speaking it is 
not the same, but work fine in a majority of cases

So, final decision will be done by Thomas on pulling to main tree.
