We're getting:

# TAP version 13
# 1..1
#   File "/tmp/code_oyWax9", line 223
#     assert tcpi_snd_wscale = 10, tcpi_snd_wscale
#                            ^
# SyntaxError: invalid syntax
# tcp_syncookies_ip6_9k.pkt: error executing code: 'python3' returned non-zero status 1

do we need to update packetdrill ?
