If we use default configuration on HW, this issue will not exist. But
our software sets the default value through i40e_filter_input_set_init.
So I think fix line need to be the commit which introduced input set
changing feature.

Acked-by: Jingjing Wu  with additional line:

Fixes: commit 98f055707685 ("i40e: configure input fields for RSS or flow 
director ")


Thanks

[dpdk-dev] [PATCH v4] net/i40e: fix hash filter invalid issue in X722

2016-10-24 Thread Jeff Guo
When verifying the Hash filtering on X722, we found a problem that
the hash value in descriptor is incorrect. The root caused is X722
uses different way of hash key word selection comparing with X710/XL710.
This patch fixes it by setting X722 specific key selection.
