2.To change RX interrupt Coalesce parameters use the ethtool -Ccommand:

#ethtool -C eth4 rx-usecs 20

#ethtool -c eth4

Coalesce parameters for eth4: Adaptive RX: off TX: off stats-block-usecs: 0 sample-interval: 0 pkt-rate-low: 0 pkt-rate-high: 0

rx-usecs: 20

rx-frames: 512

rx-usecs-irq: 0

rx-frames-irq: 512

tx-usecs: 0

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

3. To get status of L4 HW checksumming, use the ethtool -kcommand:

#ethtool -k eth4

Offload parameters for eth4:

Cannot get device tcp segmentation offload settings: Operation not supported

rx-checksumming: on

tx-checksumming: on

scatter-gather: off

tcp segmentation offload: off
