Add "rx_queue_mapping" to bpf_sock. This gives read access for the existing field (sk_rx_queue_mapping) of struct sock from bpf_sock. Semantics for the bpf_sock rx_queue_mapping access are similar to sk_rx_queue_get(), i.e the value NO_QUEUE_MAPPING is not allowed and -1 is returned in that case. This is useful for transmit queue selection based on the received queue index which is cached in the socket in the receive path. v3: Addressed review comments to add usecase in patch description, and fixed default value for rx_queue_mapping. v2: fixed build error for CONFIG_XPS wrapping, reported by kbuild test robot <lkp@intel.com> Signed-off-by:
