ConnectX-4 adapters do not have a constant indirection table size, which is set at runtime from the number of RX queues. The maximum size is retrieved using a hardware query and is normally 512. Since the current RETA API cannot handle a variable size, any query/update command causes it to be silently updated to RSS_INDIRECTION_TABLE_SIZE entries regardless of the original size. Also due to the underlying type of the configuration structure, the maximum size is limited to RSS_INDIRECTION_TABLE_SIZE (currently 128, at most 256 entries). A port stop/start must be done to apply the new RETA configuration. Signed-off-by: Nelio Laranjeiro <nelio.laranjeiro@6wind.com>
