Message-ID: <MN2PR12MB437541064CC79691A959E97ABBE30@MN2PR12MB4375.namprd12.prod.outlook.com> (raw)

Hi Ferruh,

The failure occur at hash_key_mask_is_same() which uses the size returned by flow_item_is_proto() for comparison.
Since the rte_flow_item_* of some types is now different than the rte_*_hdr size of these types, need to use the rte_*_hdr size.

Regards,
Dekel
