[Olsr-dev] BMF in 0.5.6-R8

as I repeatedly emphasized on: dyn_gw is only usable on edge-nodes (that is: 
no other mesh user behind). If you have a GW node in the middle and the GW's 
local inet does not work, other users will have trouble to use a backup 
gateway. Example: if GW fails and does not clear failed default route then:

UserNode -> GW(faulty) -> 2.GW (no inet for user)

For that reason (and for doing the necessary policy routing tricks in a shell 
script) the dyn_gw_plain exists which simply links default route in default 
routing table to HNA0/0 announcements. 

On the other hand: dyn_gw is old and unmaintained and may deserve a bit 
cleaning anyhow. Thank you,
