[openib-general] IPoIB breaks

[Josh England]

I'm getting great numbers from IPoIB...right up until it dies.

The system is x86_64 and PCIe with latest stuff under 2.6.10.  Streaming
tests with both netperf and NetPIPE die almost instantly (NetPIPE
actually lasts for a couple iterations).  Ping-pong tests with NetPIPE
seem to consistently die when it starts sending message sizes around 2k.

Running pings eventually time out with: 
ping: sendmsg: No buffer space available

IPoIB stops working completely until the module is reloaded on both
nodes.  Any ideas?
