# role: Sets the process as a talker or listener. Valid values are
# talker or listener
role = listener

# initial_state: Specify whether the talker or listener should be
# running or stopped on startup.  Valid values are running or stopped.
# If not specified, the default will depend on how the talker or
# listener is launched.
initial_state = stopped

# stream_addr: Used on the listener and should be set to the
# mac address of the talker.

# stream_uid: The unique stream ID. The talker and listener must
# both have this set the same.
#stream_uid = 0

# dest_addr: When SRP is being used the destination address only needs to
# be set in the talker.  If SRP is not being used the destination address
# needs to be set in both side the talker and listener.
# The destination is a multicast address, not a real MAC address, so it
# does not match the talker or listener's interface MAC.  There are
# several pools of those addresses for use by AVTP defined in 1722.
# At this time they need to be locally administered and must be in the range
# of 91:E0:F0:00:FE:00 - 91:E0:F0:00:FE:FF.

# max_transit_usec: Allows manually specifying a maximum transit time.
# On the talker this value is added to the PTP walltime to create the AVTP Timestamp.
# On the listener this value is used to validate an expected valid timestamp range.
# Note: For the listener the map_nv_item_count value must be set large enough to
# allow buffering at least as many AVTP packets that can be transmitted  during this
# max transit time.
