according to the nfe(4) manual page, it supports the hw.nfe.msix_disable
and hw.nfe.msi_disable loader tunables.  i don't know anything about
nfe(4) specifically, but some other network cards (such as alc(4)) have
issues with MSI or MSI-X enabled, so it might be worth turning those off
in /boot/loader.conf to see if that makes any difference.

for example:

hw.nfe.msi_disable=1
hw.nfe.msix_disable=1
