Collection of improvements found during development of XDP support.
Hopefully the last patch series before the XDP support.

ethtool_get_channels() is needed for automatic TAPRIO configuration in
combination with multiple queues.

Rework of the RX buffer allocation is prework of XDP. It ensures that
packets are only dropped if RX queue would otherwise run empty because
of failed allocations. So it should reduce the number of dropped packets
under low memory conditions.

v2:
- post rotten packet fix separately (Jakub Kicinski)
- implement ethtool::get_coalesce / set_coalesce (Jakub Kicinski)

Gerhard Engleder (4):
  tsnep: Consistent naming of struct net_device
  tsnep: Add ethtool::get_channels support
  tsnep: Throttle interrupts
  tsnep: Rework RX buffer allocation
