So am I understanding correctly -- this is other work that is
independent of GSO? Is the plan to add a new optional driver method
that e

How does that work? GSO doesn't change the hard_start_xmit()
interface, does it?

Good. Then after enabling GSO, we can chain multiple packets together in IPoIB for one doorbell to send large packet.

Hi, Roland,
If we only support GSO enablement in ethtool, there is no problem. What I meant is anything related to MAC address in ethtool utility needs to be updated for IB device.
Do you like the idea to add ethtool support in IPoIB? Do you want me to work on this?
Thanks

Is this really even true? Surely ethtool supports people who rename
their ethX interfaces to something else, even ibX? For example on my
system I can do the following:
# ip link se

ethtool is an ethernet device tool. It's OK to partically implement ethtool operations in IPoIB. We also need to patch the userlevel utility to support ibX interface.

No, I don't think anyone looked at that yet. Could you post your
patch? What is required? Supporting gather/scatter?

Since linux 2.6.18 supports GSO, I have patched IPoIB to enable GSO, but haven't tested the performance yet. Has anyone tried already?
