 6 | KNOW SUPPORTED DEVICES:
 7 |   - TP-LINK MR3020  (wifi0: Atheros 9380)
 8 |   - TP-LINK MR3040  
 9 |   - MikroTek RB411Uha
10 |   - TP-LINK WR842ND 
11 | 
12 |   - Linksys WRT54GL; tested trunk image. Works as relay only; no IPv6 support in Trunk
13 | 
14 | OPENWRT-PACKAGE DEPENDENCIES:
15 |   kmod-batman-adv  (this depends on kmod-lib-crc16) 
16 |   wireless-tools
17 | 
18 | DEBIAN DEPENDENCIES:
19 |   batman-adv seems to be installed on default. You need to install batctl, if that script is not available
20 |   this script tries to setup everything using the sys/class interface
21 | 
22 | WHAT DO THIS PACKAGE?:
23 |   - It installs on script with all needed defaults running in Mesh mode
24 |   - Script set up everything needed to get the Box in Mesh mode 
25 |   - Box in Mesh don't have to be a AP at same time
26 | 
27 | WHY AN EXTRA PACKAGE?:
28 |   - I don't want to add the Mesh-software dependency to the normal PB-Package
29 |   - Easier Update if something changes
30 | 
31 | 
32 | NOTEBOOK?:
33 |  - Not every notebook can hold two network-interfaces online
34 |  - You can join the network download this <on Work> and do <on work>
35 |  - currently there is no iptables included. You won't be able to route
36 |  - Software needed: iw, ifconfig, bridge-utils like br-ctl  & iptables Including support for "Bridge-nf"  in some cases
37 | 
38 | FAQ:
39 | 
40 | I'm getting a "SIOCSIFFLAGS: No buffer space available" - what is this?
41 |    - It seems you card cannot run with an exchanged MACAdress, switch it 
42 | off.
43 |    - Remember runnin <scriptname> stop to clean up the partly created stuff
44 |
