I already disabled the checksum, the vtnet config is: ifconfig vtnet1 -txcsum -rxcsum -tso4 -tso6 -lro -txcsum6 -rxcsum6 -vlanmtu -vlanhwtag -vlanhwfilter -vlanhwtso -vlanhwcsum up promisc vtnet1: flags=28943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST,PPROMISC> metric 0 mtu 1500 options=1800a8<VLAN_MTU,JUMBO_MTU,VLAN_HWCSUM,LINKSTATE,NETMAP> ether 0e:bd:ec:7a:08:06 media: Ethernet 10Gbase-T <full-duplex> status: active nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL> Sorry for not having posted vtnet config before. PS: VLAN_HWCSUM is not switchable off for some reason! the problem is not that.
