  Secondary process depends on the vector offload flag to select right
Rx offload path. This patch adds a variable in share memory to store
the vector offload flag that can be directly read by secondary process.

Fixes: 808a17b3c1e6 ("net/ice: add Rx AVX512 offload path")
Cc: stable@dpdk.org

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)..

Ok, I'll update it in V3.
