Viacheslav Ovsiienko bef7c9ff28 ethdev: announce migration to generic flow modify action 
The generic RTE_FLOW_ACTION_TYPE_MODIFY_FIELD action was
introduced by [1]. This action provides an unified way
to perform various arithmetic and transfer operations over
packet network header fields and packet metadata.

[1] 73b68f4c54 ("ethdev: introduce generic modify flow action")

On other side there are a bunch of multiple legacy actions,
that can be superseded by the generic MODIFY_FIELD action:

RTE_FLOW_ACTION_TYPE_OF_SET_MPLS_TTL
RTE_FLOW_ACTION_TYPE_OF_DEC_MPLS_TTL
RTE_FLOW_ACTION_TYPE_OF_SET_NW_TTL
RTE_FLOW_ACTION_TYPE_OF_DEC_NW_TTL      sfc
RTE_FLOW_ACTION_TYPE_OF_COPY_TTL_OUT
RTE_FLOW_ACTION_TYPE_OF_COPY_TTL_IN
RTE_FLOW_ACTION_TYPE_SET_IPV4_SRC       bnxt, cxgbe, mlx5
RTE_FLOW_ACTION_TYPE_SET_IPV4_DST       bnxt, cxgbe, mlx5
RTE_FLOW_ACTION_TYPE_SET_IPV6_SRC       cxgbe, mlx5
RTE_FLOW_ACTION_TYPE_SET_IPV6_DST       cxgbe, mlx5
RTE_FLOW_ACTION_TYPE_SET_TP_SRC         cxgbe, mlx5
RTE_FLOW_ACTION_TYPE_SET_TP_DST         cxgbe, mlx5
RTE_FLOW_ACTION_TYPE_DEC_TTL            mlx5, sfc
RTE_FLOW_ACTION_TYPE_SET_TTL            mlx5
RTE_FLOW_ACTION_TYPE_SET_MAC_SRC        cxgbe, mlx5
RTE_FLOW_ACTION_TYPE_SET_MAC_DST        cxgbe, mlx5
RTE_FLOW_ACTION_TYPE_INC_TCP_SEQ        mlx5
RTE_FLOW_ACTION_TYPE_DEC_TCP_SEQ        mlx5
RTE_FLOW_ACTION_TYPE_INC_TCP_ACK        mlx5
RTE_FLOW_ACTION_TYPE_DEC_TCP_ACK        mlx5
RTE_FLOW_ACTION_TYPE_SET_IPV4_DSCP      mlx5
RTE_FLOW_ACTION_TYPE_SET_IPV6_DSCP      mlx5
RTE_FLOW_ACTION_TYPE_OF_SET_VLAN_VID    bnxt, cnxk, cxgbe, enic,
                                        mlx5, octeontx2, sfc
RTE_FLOW_ACTION_TYPE_OF_SET_VLAN_PCP    bnxt, cnxk, cxgbe, enic,
                                        mlx5, octeontx2, sfc
RTE_FLOW_ACTION_TYPE_SET_TAG            mlx5
RTE_FLOW_ACTION_TYPE_SET_META           mlx5

This note deprecates the following RTE Flow actions,
as not supported by any of PMDs:

RTE_FLOW_ACTION_TYPE_OF_SET_MPLS_TTL
RTE_FLOW_ACTION_TYPE_OF_DEC_MPLS_TTL
RTE_FLOW_ACTION_TYPE_OF_SET_NW_TTL
RTE_FLOW_ACTION_TYPE_OF_COPY_TTL_OUT
RTE_FLOW_ACTION_TYPE_OF_COPY_TTL_IN

The following actions are supposed to be deprecated in 22.07
and replaced by generic field modify action:

RTE_FLOW_ACTION_TYPE_OF_DEC_NW_TTL
RTE_FLOW_ACTION_TYPE_SET_IPV4_SRC
RTE_FLOW_ACTION_TYPE_SET_IPV4_DST
RTE_FLOW_ACTION_TYPE_SET_IPV6_SRC
RTE_FLOW_ACTION_TYPE_SET_IPV6_DST
RTE_FLOW_ACTION_TYPE_SET_TP_SRC
RTE_FLOW_ACTION_TYPE_SET_TP_DST
RTE_FLOW_ACTION_TYPE_DEC_TTL
RTE_FLOW_ACTION_TYPE_SET_TTL
RTE_FLOW_ACTION_TYPE_SET_MAC_SRC
RTE_FLOW_ACTION_TYPE_SET_MAC_DST
RTE_FLOW_ACTION_TYPE_INC_TCP_SEQ
RTE_FLOW_ACTION_TYPE_DEC_TCP_SEQ
RTE_FLOW_ACTION_TYPE_INC_TCP_ACK
RTE_FLOW_ACTION_TYPE_DEC_TCP_ACK
RTE_FLOW_ACTION_TYPE_SET_IPV4_DSCP
RTE_FLOW_ACTION_TYPE_SET_IPV6_DSCP
RTE_FLOW_ACTION_TYPE_SET_TAG
RTE_FLOW_ACTION_TYPE_SET_META

The VLAN set actions are interrelated to VLAN header insertion/removal
and supported by multiple PMDs and widely used by applications and
not supposed to be deprecated due to potential large impact on
drivers and applications.
