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 providing the RSS hash type.
Patchset also disables all bpf_printk's from xdp_hw_metadata program
that we expect driver developers to use. Instead counters are introduced
for relaying e.g. skip and fail info to end-user, this can be further
debugged by re-enabling bpf_printk (when driver devel troubleshoot).
