# Usage:
# /bin/bash <test-acl-binary> <dir-with-acl-rules-traces> <acl-alg> <burst-size>
# Expected file-naming conventions:
#   - for rules: 'acl[0-9]v[4,6]_[0-9,a-z]+_rule'
#   - for traces: 'acl[0-9]v[4,6]_[0-9,a-z]+_trace'
# Each rule file expects to have exactly one trace file.
# test-acl app follows classbench file format.
# Each line defines exactly one rule/trace.
# rules record format:
# '@'<src_ip_addr>'/'<masklen><space> \
# <dst_ipv4_addr>'/'<masklen><space> \
# <src_port_low><space>":"<src_port_high><space> \
# <dst_port_low><space>":"<dst_port_high><space> \
# <proto>'/'<mask>
# trace record format:
# <src_ip_addr><space><dst_ip_addr><space> \
# <src_port><space<dst_port><space><proto>...<rule_id>
#
# As an example:
# /bin/bash app/test-acl/test-acl.sh build/app/dpdk-test-acl \
# app/test-acl/input scalar 32
#
# Refer to test-acl app for more information about rules/trace files format,
