doc: announce change to ethdev modify action data

Browse Source 
In the current implementation,
the action rte_flow_action_modify_field is not well defined
for fields larger than 64 bits (for example IPv6 source)
In addition, the byte order is also not well defined.

Both of those issue should be fixed.

as deprecated in DPDK 20.11, along with the associated macros ``ETH_MIRROR_*``.
This API will be fully removed in DPDK 21.11.
* ethdev: The struct ``rte_flow_action_modify_data`` will be modified
to support modifying fields larger than 64 bits.
In addition, documentation will be updated to clarify byte order.
* ethdev: Attribute ``shared`` of the ``struct rte_flow_action_count``
is deprecated and will be removed in DPDK 21.11. Shared counters should
be managed using shared actions API (``rte_flow_shared_action_create`` etc).
