Flow MARK item is newly supported along with MARK action. MARK
action and item are supported on both Rx and Tx. It works on the
metadata reg_c[] only if extensive flow metadata register is
supported. Without the support, MARK action behaves same as
before - valid only on Rx and no MARK item is valid.

FLAG action is also modified accordingly. FLAG action is
supported on both Rx and Tx via reg_c[] if extensive flow
metadata register is supported.

However, the new MARK/FLAG item and action are currently
disabled until register copy on loopback is supported by
forthcoming patches.

The actual index of engaged metadata reg_c[] register to
support FLAG/MARK actions depends on dv_xmeta_en devarg value.

For extensive metadata mode 1 the reg_c[1] is used and
transitive MARK data width is 24. For extensive metadata mode 2
the reg_c[0] is used and transitive MARK data width might be
restricted to 0 or 16 bits, depending on kernel usage of reg_c[0].
The actual supported width can be discovered by series of trials
with rte_flow_validate().
