[openib-general] IB Driver Initialization of FMR methods

[Tom Tucker]

I've noticed that in the IB driver, the FMR methods 
are not initialized if the XX_FLAG_FRM bit is not set 
in the device structure. My assumption at this point is 
that these methods are not present if they are not 
supported by the device. 

What's confusing is that the verbs do not check if the 
function ptr is null when involking the underlying method. 
I would have expected, that a method would be initialized 
that returned ENOSYS in this case. Any explanation as to 
the intended design point for FMR initialization would be 
greatly appreciated.

Thanks,

Tom T.
