It is just unfortunate to make such an IB-centric statement.
I will ask the same question back to you - why didn't you consider
RNICs when the IB APIs were designed a year ago? If that was considered
a year ago, We wouldn't have this problem today, right? Nothing
can be designed if we don't know what exactly need to be done for RNICs
a year ago. The real answer is because it was too early to adopt RNIC-verbs
at that time when the specs were still evolving in standard bodies
(RDMAC/IETF).

Again because we have developed something a year ago doesn't mean that
we will have to live with that interface forever. Of course,
the question is when and why should this change? As it was discussed
before, we would like to see the common PI developed without
impacting the IB development.

Thanks
Venkat
