Thanks for the patch, you will probably want this fix backported in
LTS versions.
If so, please add a Fixes: tag and Cc: stable at dpdk.org.
I guess here, it is:
Fixes: 40d5676ff1ea ("net/vmxnet3: fix initialization on FreeBSD")

Cc: Bruce

Reading again the commitlog, I wonder if we should error out in
vmxnet3_configure_msix() if rx (and/or lsc) interrupts are requested
for FreeBSD.
Did you consider this approach?
