** Description changed: + SRU Justification + + Impact: CONFIG_NETWORK_PHY_TIMESTAMPING is disabled, preventing PTP time + synchronization using the DP83640 PHYTER. + + Fix: Enable this option and set CONFIG_DP83640_PHY=m to enable the + DP83640 PHYTER driver. + + Regression Potential: The kconfig help text warns of adding overhead to + network tx and rx, but our analysis finds this to be negligible (see + comment #6). Beyond this we are enabling a new driver which does little + unless timestamping is explicitly activated, so regressions are not + expected. + + --- + Hi folks, is there a reason we do not enable CONFIG_NETWORK_PHY_TIMESTAMPING ? I'm not sure of the tradeoffs but I think this config option is required for PTP time syncronization which would be useful in telco and financial (and OCD :)) environments.
