Don't need too. GSO only improves sender side performance. It allows large
packet send in ULPs, and segments this packet in interface layer before
driver xmit. The GSO enablement is through ethtool. Since ipoib doesn't
support ethtool, i just simply added a module parameter to set the
interface GSO flag when loading the module. My next step is to enable
gather/scatter in ipoib send to chain multiple packets together for one
door bell.

Thanks
