 - ctb and moench Fw fixed (to work with pattern commdand) )addreess length
 - setting rx_hostname (or udp_dstip with rx_hostname not none) will always set udp_dstmac. solves problem of chaing udp_dstip and udp_dstmac stays the same
 - jungfrau reset core and usleep removed (fix for 6.1.1 is now fixed in firmware)
