No, it doesn't fix the problem. I tried it too.

At the moment what does fix it (with an unmodified "bus_dmamap_sync" ) is in
the fxp driver
(if_fxp.c) "fxp_intr" function, the first occurrence of "bus_dmamap_sync"
after "rcvloop:"
which is originally
bus_dmamap_sync(BUS_DMASYNC_POSTREAD|BUS_DMASYNC_POSTWRITE);

If ONLY this occurrence is changed to:

bus_dmamap_sync(BUS_DMASYNC_PREREAD) to force a cache purge before
processing incoming ethernet frames.

Then the driver works OK. For the time being, we are using the driver like
this.

Thanks
