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-high: 0 rx-frame-high: 0 tx-usecs-high: 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 pkt-rate-low: n/a pkt-rate-high: 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 stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a

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
