The patch to enable this is not big - I will produce one and send it to
the list. Might not happen before next week.
What mtu are you using?
9000.
BTW, I don't think I followed up on this to the list.
The reason for the crummy throughput above was because
the Chelsio cards were in PCIe x4 slots (*blush*).
Once in x8 slots, netperf SDP_STREAM looks like this:
SDP STREAM TEST from 128.227.253.92 (128.227.253.92) port 0 AF_INET to
128.227.253.91 (128.227.253.91) port 0 AF_INET : cpu bind

Am summarizing on a web page now.
