Can we make the type/ name more specific, how about defined as: "bool
rx_vec_offload_support;" ?
Then we can keep most thing unchanged in primary process branch, but only add
below ,
ad->rx_vec_offload_support = (rx_check_ret == ICE_VECTOR_OFFLOAD_PATH);
in following branch
we can avoid duplicate if (rx_check_ret == ICE_VECTOR_OFFLOAD_PATH)..
