[ofa-general] umad agent question?

[Robert Pearson]

Sean,

When I set vendor class to 15 instead of 9 everything works much better. I
suspect this means someone else is registered for 9. In that case the
register agent call should probably have not succeeded.

The TID still gets clobbered and the QKEY ignored somewhere.

The method mask is only used for routing received unsolicited MADs. 
I.e. those that are not response MADs.  Any app can send a MAD and get 
its response.  Only one app is allowed to receive a non-response MAD.

As for the problem that you mention, I don't understand the behavior 
that you're seeing.
