[etherlab-dev] Bus scan takes long time at low rates

Hi Steffen

In the idle phase, the transmitting of the frame is done by a internal 
thread of the master which runs as fast as the bus allows.
The transmitting of the frame in cyclic phase is done within the 
realtime thread (i.e. within the calls to ecrt_master_send/receive) to 
ensure proper cyclic transmission of process data.

Why do you need to do a rescan in cyclic mode? You should leave cyclic 
mode if the number of slaves on the changes. The master will then scan 
the bus automatically.
