Gatis Peisenieks a1150a04b7 atl1c: move tx cleanup processing out of interrupt 
Tx queue cleanup happens in interrupt handler on same core as rx queue
processing. Both can take considerable amount of processing in high
packet-per-second scenarios.

Sending big amounts of packets can stall the rx processing which is
unfair and also can lead to out-of-memory condition since
__dev_kfree_skb_irq queues the skbs for later kfree in softirq which
is not allowed to happen with heavy load in interrupt handler.

This puts tx cleanup in its own napi and enables threaded napi to
allow the rx/tx queue processing to happen on different cores.

The ability to sustain equal amounts of tx/rx traffic increased:
from 280Kpps to 1130Kpps on Threadripper 3960X with upcoming
Mikrotik 10/25G NIC,
from 520Kpps to 850Kpps on Intel i3-3320 with Mikrotik RB44Ge adapter.
