Hi Rich,

Sorry for not getting back to you sooner.

I had another look a this, and I cannot reproduce. Whenever my DHCP
lease is renewed, this is immediately reflected in the lft_valid. I
added a bit more debugging to networkd, so if you are able to
reproduce this with current git, please post your debug logs.
