====================
sfc: per-queue stats

This series implements the netdev_stat_ops interface for per-queue
 statistics in the sfc driver, partly using existing counters that
 were originally added for ethtool -S output.

Changed in v4:
* remove RFC tags

Changed in v3:
* make TX stats count completions rather than enqueues
* add new patch #4 to account for XDP TX separately from netdev
  traffic and include it in base_stats
* move the tx_queue->old_* members out of the fastpath cachelines
* note on patch #6 that our hw_gso stats still count enqueues
* RFC since net-next is closed right now

Changed in v2:
* exclude (dedicated) XDP TXQ stats from per-queue TX stats
* explain patch #3 better
