"MprCoverage 7" is just a legacy way to say "switch MPR selection off". It has 
been used by most Freifunk networks. "MprCoverage 3" should be the same in 
most networks, unless you have two routers that have at least 4 different 
connections through another router between them.

Difficult. The easiest way would be to use "ebtables" and a bridge, but you 
cannot emulate packet loss with this.
