Tested by using a pcs script to inject the test vectors into ixgbe and
igb interfaces, and using a kernel printf to dump the RSS hash from
the mbuf flowid on packet reception to verify the hash value is correct.
The kernel toeplitz hash routine was tested with a user-space harness
that verified the hash results.
It is recommended that the pcs script be used when implementing RSS on
new NICs, and that the user-space test harness be used when modifying
the toeplitz hash routine.
