why this specific initialization but not in nes or amso1100? I
think the device structure is zeroed out on allocation anyway.
To prevent confusion, lets have it documented somewhere that in the
iwarp case IB_DEVICE_LOCAL_DMA_LKEY refers to zero-stag and as the
name suggest its an lkey which equals zero, how does this sound?
I don't see the benefit. Folks can read the RDMA Consortium verbs if
they want to understand about 0 stag.
Steve.
I can add a comment in the code above if you think that's necessary.
Something like:
/*
* Use stag 0 for the global local access lkey.
*/
