Sagi,
As you mentioned the IO path is different in SRP and iSER so IMO we 
should start with SRP debugging. NVMf is similar to iSER (and not SRP) 
and that's why I think we can apply this patchset.
If you want to wait till we debug SRP issue it's fine, but I can't repro 
it in my lab so it can take longer.

Lourance,
maybe you can update your FW to the latest CX4 from our site and try to 
repro this issue ?

thanks,
Max.
