This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- bionic' to 'verification-done-bionic'. If the problem still exists, change the tag 'verification-needed-bionic' to 'verification-failed- bionic'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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.
