# OVN_CHECK_PACKETS([PCAP], [EXPECTED])
#
# This compares packets read from PCAP, in pcap format, to those read
# from EXPECTED, which is a text file containing packets as hex
# strings, one per line.  If PCAP contains fewer packets than
# EXPECTED, it waits up to 10 seconds for more packets to appear.
#
# The implementation is an m4 macro that is mostly implemented in
# terms of a shell function.  This reduces the size of the generated
# testsuite file since the shell function is only emitted once even
# when this macro is invoked many times.
