--- Comment #4 from Harald Schmalzbauer <bugzilla.freebsd at omnilan.de> ---
tested with RC1:
Still same panic as soon as if_vmx(4) get's load _and_ jumbo frames are in use
(mtu 9000).

Unfortunately, solid vmxnet3 support is crucial to my setups.
I managed to patch the vmware vmxnet3 guest driver to work with FreeBSD 12, but
it also suffers from panics…
The vmware vmxnet3 driver provides doubled transfer rates compared to
if_vmx(3), but my skills and time don't last to fix any of both myself.

In case anyone is interested in the vmxnet3 patch I'll provide on request of
course, but won't pollute this bug report with anything completely different.
