hayes# ifconfig xl0
xl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        options=9<RXCSUM,VLAN_MTU>
        inet 192.168.0.1 netmask 0xffffff00 broadcast 192.168.0.255
        inet6 fe80::250:daff:fe42:fc4%xl0 prefixlen 64 scopeid 0x1
        ether 00:50:da:42:0f:c4
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active


the tx checksum offloading is not  enabled y default at boot and :
ifconfig xl0 txcsum 
give me this message:

hayes# ifconfig xl0 txcsum
ifconfig: txcsum: Invalid argument


nota: the rxcsum and -rxcsum  flags are working, and -txcsum  has no 
error messages


any ideas?
