Refactor and unify partner-TXQ handling in the EF100 and legacy drivers.

The main thrust of this series is to remove from the legacy (Siena/EF10)
 driver the assumption that a netdev TX queue has precisely two hardware
 TXQs (checksummed and unchecksummed) associated with it, so that in
 future we can have more (e.g. for handling inner-header checksums) or
 fewer (e.g. to free up hardware queues for XDP usage).

Edward Cree (5):
  sfc: add and use efx_tx_send_pending in tx.c
  sfc: use tx_queue->old_read_count in EF100 TX path
  sfc: use efx_channel_tx_[old_]fill_level() in Siena/EF10 TX datapath
  sfc: rewrite efx_tx_may_pio
  sfc: remove efx_tx_queue_partner
