Subject: [PATCH 420/431] net/hns3: disable SCTP verification tag for RSS hash
input
[ upstream commit 47d5fa9a91989c4671ecb8c3a7e767572846570c ]
When the symmetric RSS algorithm is used, the same packet is
expected to be hashed to the same queue in the upstream and
downstream directions.
The problem is that it could map the packets in the same SCTP
connection to different NIC RX queues depending on the direction
of packets. This is because the verification Tag is used as the
RSS hash input for the SCTP packets, and the value depends on the
peer end of the SCTP connection and could not be symmetrically
used in the hardware-implemented RSS algorithm.
In addition, the ethdev framework doesn't support setting SCTP
V-tag as the RSS hash input. So disable it for all RSS hash
algorithms.
