Understanding Flow API action RSS

[Ivan Malov]

Hi all,

In 'rte_flow.h', there is 'struct rte_flow_action_rss'. In it, 'queue' is
to provide "Queue indices to use". But it is unclear whether the order of 
elements is meaningful or not. Does that matter? Can queue indices repeat?

An ethdev may have "global" RSS setting with an indirection table of some
fixed size (say, 512). In what comes to flow rules, does that size matter?

When the user selects 'RTE_ETH_HASH_FUNCTION_DEFAULT' in action RSS, does
that allow the PMD to configure an arbitrary, non-Toeplitz hash algorithm?

Please advise.
