Excuse me, I miss why you need a check before setting the bit.

Currently, none of the PMDs support disabling RSS_HASH (except octeontx2) since it involves 
adding an if check in Rx routine that might lead to perf impact.
So, we are implicitly enabling the offload for all the PMDs if an application decides to disable
RSS_HASH. In future if PMD maintainer decides to add this feature she/he can remove the check.

As I understand Thomas says that it is just sufficient to do:
    dev->data->dev_conf.rxmode.offloads |= DEV_RX_OFFLOAD_RSS_HASH;
without any if before.

Yes, it is true since right now it looks a bit strange.
I guess it is the result of code evolution. Initially
it was logging inside if, but logging is moved to ethdev.

(Of course, it is true for such trivial checks only)

Hi,

mvpp2 and mvneta PMDs are also support RSS hash.
Please add them to the patch.

Regards,
Liron
