Point of order here, per the commiters guide you do not have the option
of seconding any motion that should of never been made, per rule 6 a
request by a Maintainer to revert your change has been made.  There
is no arguing on that point.

The code was committed to ^head 3 weeks ago, I dont care if it was
written 10 years ago, for this type of change and giving the current
issues that users of iflib based drivers are facing in stable/12 and
releng/12.0 I want this code out of stable/12 until we address and
verify that we have solved these other issues.

None of this is an emergency, it is a simple mater of vmxnet3 is working
just fine, has been working just fine for a very long time, and is of know
quality.  What however is defanitly NOT an emergency is getting some new
iflib'ed version of this driver in the stable branch when we already have
issues in that branch with all the other iflibed drivers.

I am now upgrading my strongly suggest you revert to a flat out
revert this commit, with hat RE on.
