Yes, I agree on that. Infact the verbs layer will return ENOSYS for mthca driver. But I was assuming that any other driver by a different hardware vendor can support this call (mthca over time could support this call too ?). > However I'm not sure I understand why the MAD layer wants to resize > these objects -- given that the number of QPs is known in advance and > that the MAD layer can choose how many work requests to post per QP, > I'm not sure what is gained by trying to resize things dynamically. Actually, I haven't really implemented the "dynamically" part, where you resize the CQ during operation. The spec said that when you create a QP, it can be larger than what you specified. If so, I see good value in increasing the size of the associated CQ, if it is supported by the driver.
