[PATCH net-next V2] virtio_net: ethtool tx napi configuration
Implement ethtool .set_coalesce (-C) and .get_coalesce (-c) handlers.
Interrupt moderation is currently not supported, so these accept and
display the default settings of 0 usec and 1 frame.
Toggle tx napi through a bit in tx-frames. So as to not interfere
with possible future interrupt moderation, value 1 means tx napi while

[RFC V7 PATCH 0/7] enable tx interrupts for virtio-net
Hi:
This is a new version of trying to enable tx interrupts for
virtio-net.
We used to try to avoid tx interrupts and orphan packets before
transmission for virtio-net. This breaks socket accounting and can
lead serveral other side effects e.g:
- Several other functions which depends on socket accounting can not
work correctly (e.g TCP Small Queue)
- No tx completion which make BQL or packet
