sfc: keep alive neighbour entries while a TC encap action is using them2023-06-23T02:54:14ZEdward Creeecree.xilinx@gmail.com2023-06-21T12:15:04Zurn:sha1:9a14f2e3dab106df7f27d1730cc540247317d4b9
When processing counter updates, if any action set using the newly
incremented counter includes an encap action, prod the corresponding
neighbouring entry to indicate to the neighbour cache that the entry
is still in use and passing traffic.

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.

Add the packet and byte counts to the software running total, and store
the latest jiffies every time the counter is bumped.

efx_tc_flower_get_counter_index() will create an MAE counter mapped to
the passed (TC filter) cookie, or increment the reference if one already
exists for that cookie.

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