The patch was generated against CURRENT so it may not cleanly apply to 8.0 due to if_timer changes. But I think you can download latest vge(4) code in CURRENT and apply the patch. Note, the patch was not tested at all on real hardware so it even may not work at all.(Long time ago, I ordered the vge(4) hardware was not delivered.) http://people.freebsd.org/~yongari/vge/vge.busdma.diff > Anyway I'm considering to purchase two more NIC cards, because I need > a quick fix... > > Regards, > -- > Yoshiaki Kasahara > Research Institute for Information Technology, Kyushu University > kasahara@nc.kyushu-u.ac.jp
