[ofa-general] RE: [rds-devel] Has anyone tried running RDS over 10GE / IWARP NICs ?

[Steve Wise]

I think RDS might be getting confused because the 10GbE rnic shows up as 
a dumb NIC hooked into the native TCP stack -and- an rdma device.

Jon Mason will be working to enable RDS soon on the chelsio device. 
He'll feed back the changes needed, if any, to RDS.  Stay tuned.

However, Scott if you want to debug this further, we can support you.

Steve.
