Current API for bpf_xdp_metadata_rx_hash() returns the raw RSS hash value, but doesn't provide information on the RSS hash type (part of 6.3-rc). This patchset proposal is to change the function call signature via adding a pointer value argument for provide the RSS hash type. Alternatively we disable bpf_xdp_metadata_rx_hash() in 6.3-rc, and have more time to nitpick the RSS hash-type bits.
