FYI:
tcpreplay -i en0 -M 30.0 -l 1000 -Kq -T abstime ./test/test.rewrite_pad
Actual: 100000 packets (70205000 bytes) sent in 18.71 seconds
Rated: 3752271.5 bps, 28.63 Mbps, 5344.74 pps
Statistics for network device: en0
Attempted packets: 100000
Successful packets: 100000
Failed packets: 0
Retried packets (ENOBUFS): 0
Retried packets (EAGAIN): 0
Looks about right to me.
