(Resending without HTML stuff)
It is from the days that SDP over RoCE wasn't stable.
In addition, when customers had a very long delay before TCP connection established, in the following scenario:
1. in libsdp.conf, setting mode to 'both' (Try SDP and fallback to TCP)
2. application tries to open socket to a remote peer connected using 10G ethernet
3. Remote host don't support RoCE.
It took few seconds till the CMA gave up trying to connect, and SDP connection failed, and TCP connection was established.
We plan to change the default state of this module parameter to enable SDP over RoCE, and to add the option to disable SDP per interface.
Currently a user can only disable SDP on a subnet/port/application.
