I see. Then it sounds like cxgb3 is busted because its not checking
this attribute. :)
Yep... grep shows none of amso1100, cxgb3, nor nes look at sq_sig_type
at all in the kernel driver. Looks like a common iWARP bug :)
As far as I can tell this is an infiniband only attribute. I do not see
it in iWarp RDMA spec, if I am wrong please point me to the right place.
How do we handle situation like this when there is a difference between
the two?
IMO its an API issue and thus really outside the scope of the iWARP RDMA
Verbs document, which doesn't define any APIs. Since it can easily be
supported (I think), I plan to add support in cxgb3. IE just add
additional logic in your post paths to check the attribute and set the
appropriate "signaled" bit for your WRs. Unless I'm missing something here?
Steve.
