ipoe,pppoe,vlan_mon: deleted conditions to simultaneous start ipoe and pppoe on same interfaces (started by vlan_mon)

If start=auto is specified then accel-pppd automatically starts session with username = interface name on shared=0 interfaces.
Use it with conjuction vlan_mon. So any packet may start session.

local-net is used to filter incomming packets which may start UP session
