I think your tcpdump is showing some problems. I see two syn packets with the same seq number initiated from the 10 host: 10.54.13.101.14196 > 172.22.0.100.https : S the first one with a correct cksum the second is incorrect and the TTL has been decremented compared to the first.
Then I see the 172 host respond with a syn-ack 172.22.0.100.https > 10.54.13.101.14196: S,...ack. But then the 172 host initiates another connection to the 10 host 172.22.0.100.46740 > 10.54.13.101.14196: S and the cksum is incorect.
Then the 10. host sends tcp resets to 172.22.0.100.https and 172.22.0.100.46740. Again one cksum is correct the other incorrect.
There is something strange happening here, not sure what it is...
