EF100 hardware supports attaching counters to action-sets in the MAE.
Use these counters to implement stats for TC flower offload.

The counters are delivered to the host over a special hardware RX queue
 which should only ever receive counter update messages, not 'real'
 network packets.

Edward Cree (11):
  sfc: add ability for an RXQ to grant credits on refill
  sfc: add start and stop methods to channels
  sfc: add ability for extra channels to receive raw RX buffers
  sfc: add ef100 MAE counter support functions
  sfc: add extra RX channel to receive MAE counter updates on ef100
  sfc: add hashtables for MAE counters and counter ID mappings
  sfc: add functions to allocate/free MAE counters
  sfc: accumulate MAE counter values from update packets
  sfc: attach an MAE counter to TC actions that need it
  sfc: validate MAE action order
  sfc: implement counters readout to TC stats
