[PATCH net-next 0/4] ethtool: extend coalesce uAPI

[Yufeng Mo]

In order to support some configuration in coalesce uAPI, this RFC
extends coalesce uAPI and add support for CQE mode.

Below is some test result with HNS3 driver:
1. old ethtool(ioctl) + new kernel:
estuary:/$ ethtool -c eth0

[PATCH net-next 1/4] ethtool: add two coalesce attributes for CQE mode

[Yufeng Mo]

Currently, there many drivers who support CQE mode configuration,
some configure it as a fixed when initialized, some provide an
interface to change it by ethtool private flags. In order make it
more generic, add two new 'ETHTOOL_A_COALESCE_USE_CQE_TX' and
'ETHTOOL_A_COALESCE_USE_CQE_RX' coalesce attributes, then these
parameters can be accessed by ethtool netlink coalesce uAPI.

+Timer reset mode (``ETHTOOL_A_COALESCE_USE_CQE_TX`` and
+``ETHTOOL_A_COALESCE_USE_CQE_RX``) controls the interaction between packet
+arrival and the various time based delay parameters. By default timers are
+expected to limit the max delay between any packet arrival/departure and a
+corresponding interrupt. In this mode timer should be started by packet
+arrival (sometimes delivery of previous interrupt) and reset when interrupt
+is delivered.
+Setting the appropriate attribute to 1 will enable ``CQE`` mode, where
+each packet event resets the timer. In this mode timer is used to force
+the interrupt if queue goes idle, while busy queues depend on the packet
+limit to trigger interrupts.

[PATCH net-next 2/4] ethtool: extend coalesce setting uAPI with CQE mode

[Yufeng Mo]

In order to support more coalesce parameters through netlink,
add an new structure kernel_ethtool_coalesce, and keep
struct ethtool_coalesce as the base(legacy) part, then the
new parameter can be added into struct kernel_ethtool_coalesce.

Also add new extack parameter for .set_coalesce and .get_coalesce
then some extra info can return to user with the netlink API.

This and the following patches don't build, please make sure
allmodconfig builds correctly. Here's an example failure, but
IDK if there isn't more:

I'd move changes to these files to the first patch, otherwise 
they're hard to find in all the driver modifications.

ok, thanks.

[PATCH net-next 3/4] net: hns3: add support for EQE/CQE mode configuration

[Yufeng Mo]

For device whose version is above V3(include V3), the GL can
select EQE or CQE mode, so adds support for it.

In CQE mode, the coalesced timer will restart when the first new
completion occurs, while in EQE mode, the timer will not restart.
