The high and low threshold are hysteresis thresholds to prevent flapping: once the high threshold has been reached, a low threshold event will be triggered only after the bandwidth usage went below the low threshold. This series adds support for receiving and exposing such events as ethtool counters. 2 new pairs of counters are exposed: pci_bw_in/outbound_high/low. These should help the user understand if the device PCI is under pressure. Planned followup patches: - Allow configuration of thresholds through devlink. - Add ethtool counter for wakeups which did not result in any state change. ==================== Link: https://patch.msgid.link/1752589821-145787-1-git-send-email-tariqt@nvidia.com Signed-off-by: Jakub Kicinski --- cd031354087d8ae005404f0c552730f0bd33ac33
