Thanks for the comment. I'll add the prefix.

Thanks for the suggestion. I'll change it.

_recv_raw_pkts_vec is used by the normal RX and scatter RX. It will be called again later in the patch 4. So, we make it an inline function.

To our experience, it can be reused when the vector is implemented on other platform. So we put it in the common.h.
