--- Comment #1 from Zhenlei Huang <zlei.huang at gmail.com> ---
Sorry but it can be also reproduced on FreeBSD 12.1-RELEASE.

It looks if there's no traffic on interface vmx0, the problem cannot be
reproduced following the above steps. Need one more step to reproduced.

Steps to reproduce:
 1. Boot VM
 2. tcpdump -ni netmap:vmx0
 3. ctrl + c to stop tcpdump, then repeat step 2
