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
Coalesce parameters for eth0:
Adaptive RX: on TX: on
stats-block-usecs: 0
sample-interval: 0
pkt-rate-low: 0
pkt-rate-high: 0
rx-usecs: 20
rx-frames: 0

tx-frame-high: 0
2. ethtool(netlink with cqe mode) + kernel without cqe mode:
estuary:/$ ethtool -c eth0
Coalesce parameters for eth0:
Adaptive RX: on TX: on
stats-block-usecs: n/a
sample-interval: n/a

tx-usecs-high: 0
tx-frame-high: n/a
CQE mode RX: n/a TX: n/a
3. ethool(netlink with cqe mode) + kernel with cqe mode:
estuary:/$ ethtool -c eth0
Coalesce parameters for eth0:
Adaptive RX: on TX: on

CQE mode RX: off TX: off
4. ethool(netlink without cqe mode) + kernel with cqe mode:
estuary:/$ ethtool -c eth0
Coalesce parameters for eth0:
Adaptive RX: on TX: on
stats-block-usecs: n/a
sample-interval: n/a
pkt-rate-low: n/a
pkt-rate-high: n/a
rx-usecs: 20

Change log:
V2 -> V3:
1. split #1 into adding new parameter and adding new attributes.
2. use NLA_POLICY_MAX(NLA_U8, 1) instead of NLA_U8.
3. modify the description of CQE in Document.
V1 -> V2:
refactor #1 in V1 suggestted by Jakub Kicinski.
Yufeng Mo (4):
ethtool: add two coalesce attributes for CQE mode
ethtool: extend coalesce setting uAPI with CQE mode
net: hns3: add support for EQE/CQE mode configuration
net: hns3: add ethtool support for CQE/EQE mode configuration
