[Stgt-devel] [ofa-general] Re: [Ips] Calculating the VA iniSER header

Both of these implementations use a non-conformant iSER header (they add write_va and read_va fields, which incidentally do not appear to be used). Are these changes documented anywhere in the IB domain, or are these variations needed for another reason?

The choice to proceed in the broken way, or to terminate the connection (with big loud error messages) is the implementor's choice. Either way, the issue is detected and corruption avoided.

Take a look at the iSER for IB annex:
