Notes similar to RSS hash. It requires better motivation why.

Also I think that flow API action MARK documentation should be updated to mentioned the offload. > Signed-off-by: Pavan Nikhilesh <pbhagavatula@marvell.com> > --- > doc/guides/nics/features.rst | 12 ++++++++++++ > lib/librte_ethdev/rte_ethdev.h | 1 + > 2 files changed, 13 insertions(+) > > diff --git a/doc/guides/nics/features.rst b/doc/guides/nics/features.rst > index f79b69b38..d67430d90 100644 > --- a/doc/guides/nics/features.rst > +++ b/doc/guides/nics/features.rst > @@ -594,6 +594,18 @@ application to set ptypes it is interested in. > * **[provides] mbuf**: ``mbuf.packet_type``. > > > +.. _nic_features_flow_action_type_update: May be _nic_features_flow_mark ? > + > +Flow type update May be "Flow mark delivery" ? > +---------------- > + > +Supports flow action type update to ``mbuf.ol_flags`` and ``mbuf.hash.fdir.hi``. > + > +* **[uses] rte_eth_rxconf,rte_eth_rxmode**: ``offloads:DEV_RX_OFFLOAD_FLOW_TYPE``.
