> Update in v2:
> - clean tabstops
> - move the json vpn out of the if because we need this after reboot
>
> Update in v5:
> !!UNTESTED!!
> - change hidden AP ip to locallink
> - Open hidden AP after more checks
> - Load json File from Gateway if Gateway in Batman in Range
>
> Update in v6:
> !!UNTESTED!!
> - fix hidden station v6
> - fix -n to -f if
> - Add function to check for a gateway and use this
> - remove /etc/community.cfg and variables
> - send fewer infos to keyxchangev2
> - add a check if /tmp/keyxchangev2 not downloadable and edit a bit on
the
> wgets
> - change the position from json_load and do this only 1 times
>
> Update in v7:
> !!UNTESTED!!
> - delete keyxchangev2data at start of the script
> - do only things with keyxchangev2data if available
> - change keyxchangev2 url
>
> Update in v8/v9:
> - rebase onto 20170918-beta
>
> Update in v10:
> - Minor code fixes
> - Added fff-hoods to fff-base Makefile
> - Removed trailing whitespaces and harmonized tabs
> - Fixed some comments spelling
> - Added mac for hostname rewrite
> - Removed redundant check for /tmp/keyxchangev2data
>
> Update in v11:
> - Changed isGatewayAvailable to return integers (bool is
> not valid) and removed brackets for evaluations
> - Added variables for channels as they are used twice
> - Fixed $radio not set at the beginning (WORKAROUND!)
> - Changed OpenWRT to LEDE
> - Correctly reset json_select before reuse
> - Some tidying-up of comments and quotes
> - Fixed vpn loop so it works for more than one host (TESTED)
> - Fixed "else" if no file received
>
> Changes in v12:
> - Removed obsolete hostname
>
> Changes in v14 (Tested, working Inet+mesh):
> - Fixed stderr redirect
> - Added call of configurehood to rc.local, so it is triggered
> if wan does not come up. To prevent race condition,
> hotplug.d is removed.
> - Added wifi call to configAP setup
> - Remove hiddenap flag after successful setup
> - Added -q to uci calls
> - Added network interface configSta
> - Substitute timestamp to enable SHA comparison
> - Removed started-check from vpn-select
>
> Changes in v15:
> - Fixed 5 GHz channel
> - Only start vpn-select if router has internet
> - Put ping into function since it is used twice
> - Check for started in micrond to prevent race condition
> - Moved copy of keyxchangev2data to the end
>
> Changes in v16:
> - Open configap for both 2.4 and 5 GHz
