Hi, 

the NIC driver for mpc85xx reports checksum offloading capabilities for the Rx direction only . From my understanding, 
the eTSEC (e.g. MPC8548) also supports Tx offloading. 
What's the reason that Tx is not offered by the driver? 

# ./ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33192
        inet 127.0.0.1 netmask 0xff000000
tsec0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        capabilities rx=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        capabilities tx=0
        enabled=0
        address: 00:e0:00:c0:00:fc
        media: Ethernet autoselect (1000baseT full-duplex)
        status: active

Thanks, 
Christopher
