[openib-general] mellanox sdr/ddr hca interoperability

[yipee]

Hi,

Can I build a fabric with a ddr switch and some hosts with sdr hcas, and other 
hosts with ddr hcas?
Are there known interoperability issues with such a fabric? All transports (ud/
rc) work as expected?
For example can a ddr host establish a connection with a sdr host and send/
receive data? Should I configure anything specifically for such a fabric?


Thanks,
y
