On FLOW_CLS_STATS, look up the MAE counter by TC cookie, and report the
change in packet and byte count since the last time FLOW_CLS_STATS read
them.

sfc: validate MAE action order2022-11-16T09:07:03ZEdward Creeecree.xilinx@gmail.com2022-11-14T13:16:00Zurn:sha1:83a187a4eb3a8d7b747e7cfd48228dbc4dbb5c92
Currently the only actions supported are COUNT and DELIVER, which can only
happen in the right order; but when more actions are added, it will be
necessary to check that they are only used in the same order in which the
hardware performs them (since the hardware API takes an action *set* in
which the order is implicit). For instance, a VLAN pop must not follow a
VLAN push. Most practical use-cases should be unaffected by these
restrictions.
Add a function efx_tc_flower_action_order_ok() that checks whether it is
appropriate to add a specified action to the existing action-set.

sfc: attach an MAE counter to TC actions that need it2022-11-16T09:07:03ZEdward Creeecree.xilinx@gmail.com2022-11-14T13:15:59Zurn:sha1:2e0f1eb05692b489bb9fdd30617b52022a93b2e3
The only actions that expect stats (that sfc HW supports) are gact shot
(drop), mirred redirect and mirred mirror. Since these are 'deliverish'
actions that end an action-set, we only require at most one counter per
action-set.

Currently there is no counter-allocating machinery to connect the
resulting counter update values to; that will be added in a
subsequent patch.
