interfaces_gre.php: Interface flags on GRE interfaces are incorrectly configured, always enabled when saving in GUI
When creating or editing a GRE interface the interface at the OS level (e.g. gre0) has all flags by default (LINK0, LINK1, LINK2) despite the GUI settings showing them disabled. Checking the boxes and saving has no effect.
When booting, the flags appear to be processed correctly.
Issue seems to be present on 2.2.x and 2.3.
I have a fix, will push momentarily.
