You're trying to fix a NIC driver-related issue by messing with your
firewall, you're most likely looking in the wrong place. May have more
luck posting to freebsd-net. One thing to try is disabling hardware
checksum offloading (rxcsum, txcsum) to see if that makes any
difference, with some NICs it causes issues.
