How to Turn 4-tuple Hash Based Steering On and Off

4-tuple hash based steering is turned on via the lanadmin -X drv_rth_on <ppa> command.

4-tuple hash based steering is turned off via the lanadmin -X drv_rth_off <ppa>.

When the 4-tuple hash based steering feature is turned on, all 8 queues on the AD385A are used; when it is turned off, port based steering uses a maximum of 4 queues, unless the user otherwise configures the number of queues.

To make the setting persistent across reboots, HP_IXGBE_4TUPLE_RTH in /etc/rc.config.d/hpixgbeconf must be set to on.

	NOTE: UDP multi-fragment packets are always steered to the default queue in both steering methods.
