Implement ethtool .set_coalesce (-C) and .get_coalesce (-c) handlers.Applied, with...
Interrupt moderation is currently not supported, so these accept and
display the default settings of 0 usec and 1 frame.
Toggle tx napi through setting tx-frames. So as to not interfere
with possible future interrupt moderation, value 1 means tx napi while
value 0 means not.
Only allow the switching when device is down for simplicity.

Changes from V2:
- only allow the switching when device is done
- remove unnecessary global variable and initialization
Changes from V1:
- try to synchronize with datapath to allow changing mode when
interface is up.
- use tx-frames 0 as to disable tx napi while tx-frames 1 to enable tx napi
+ bool running = netif_running(dev);this unused variable removed.
