Delete static address after switching to DHCP
I have an interface where it was using a static IP/24 configuration. I wanted to switch it back to DHCP, so I checked DHCP in the webgui (the checkbox), but did not clear the fields for IP or Subnet Mask, so the old static IP and Subnet Mask was still "populating" the field, but were greyed out. After hitting save/apply, I got a DHCP IP on that interface, HOWEVER that same interface also kept the static IP and Subnet Mask, AND the old static IP was able to serve me webGUI content and do stuff.
This seems like a bug to me, but if it is working as intended, perhaps make it so the user knows this will happen?
