Subject: [RFC net-next 0/4] ethtool: extend coalesce uAPI
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
rx-usecs-irq: 0
rx-frames-irq: 0
tx-usecs: 20
tx-frames: 0
tx-usecs-irq: 0
tx-frames-irq: 0
rx-usecs-low: 0
rx-frame-low: 0
tx-usecs-low: 0
tx-frame-low: 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
rx-usecs: 20
rx-frames: 0
rx-usecs-irq: n/a
rx-frames-irq: n/a
tx-usecs: 20
tx-frames: 0
tx-usecs-irq: n/a
tx-frames-irq: n/a
rx-usecs-low: n/a
rx-frame-low: n/a
tx-usecs-low: n/a
tx-frame-low: n/a
rx-usecs-high: 0
rx-frame-high: 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
stats-block-usecs: n/a
sample-interval: n/a
pkt-rate-low: n/a
pkt-rate-high: n/a
rx-usecs: 20
rx-frames: 0
rx-usecs-irq: n/a
rx-frames-irq: n/a
tx-usecs: 20
tx-frames: 0
tx-usecs-irq: n/a
tx-frames-irq: n/a
rx-usecs-low: n/a
rx-frame-low: n/a
tx-usecs-low: n/a
tx-frame-low: n/a
rx-usecs-high: 0
rx-frame-high: n/a
tx-usecs-high: 0
tx-frame-high: n/a
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
rx-frames: 0
rx-usecs-irq: n/a
rx-frames-irq: n/a
tx-usecs: 20
tx-frames: 0
tx-usecs-irq: n/a
tx-frames-irq: n/a
rx-usecs-low: n/a
rx-frame-low: n/a
