dpdk/ixgbe: setup RSS for Intel IXGBE PMD

Set RSS hash function according to Intel IXGBE PMD available hash functions.

During configuration, a warning appeared stating that RSS hash function
has been changed from one value to the other. This has meant that
the supported hash functions did not cover all required hash functions
by the configuration. This commit solves the warning.
