The i40e hardware has support for SCTP filtering via Rx NFC however the
default configuration expects us to include the verification tag as a part
of the filter.  In order to support that I need to be able to transfer that
data through the ethtool interface via a new structure.

This patch adds a new structure to allow us to pass the verification tag
for IPv4 or IPv6 SCTP traffic.

This looks like an incompatible ABI change.  I suppose it could be OK
if no drivers implemented flow steering for SCTP using the previously
specified structure, but have you checked that that is the case?
