# Traffic-insight marker subsystem (compute side).
#
# ubridge's ``marker`` module is a passive tap: on a BPF match it emits a UDP
# ``MARK`` signal to a configured sink and/or appends the packet to a pcap.
# This package owns the compute-side UDP sink: one listener per compute process
# serves every ubridge on that host, disambiguated by ``node=<id>``.
