            Bug ID: 1113
           Summary: i40e: device configure ignores RSS key in rx_adv_conf
           Product: DPDK
           Version: unspecified
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: ethdev
          Assignee: dev@dpdk.org
          Reporter: ivan.malov@oktetlabs.ru
  Target Milestone: ---

Running the opensource ethdev test suite [1] on a i40e rig suggests that the
PMD
might have a bug in its device configure method. In particular, RSS key size
and
data passed by the caller as part of "rx_adv_conf" seem to be completely
ignored.

If the caller makes a mistake in the key size, they won't be informed about
that.
This way, the caller may be tricked into thinking that "rx_adv_conf" is
accepted.
However, if they try to predict a hash using this key, the result won't be
valid.

A log example can be found at [2].
