I believe it is due to updates to the FXP driver that allow checksumming for tx/rx. My guess is checksumming is enabled by default and you (and I) happen to have the cards recognized by FXP that do not support it. (The BAD in the ipf log represents bad checksum) If you do "ifconfig fxp0 -txcsum -rxcsum" your problem should go away. For /etc/rc.conf, just add -txcsum -rxcsum to the interface definition.
