Add menu entry for plugins to more easily distinguish phases of plugins activation/installation states.  Add, hopefully, support for jumbo frames on the nics.  May not be perfect and may need to revert those changes, but hopefully it will retrograde to mtu 1500 as needed though a few errors may be printered.
