Hi
Good questions Joe!
And good someone else brought this up, because I guess it's not meant to me.
And it looks however now that I've done quite a few more patches that
there should not have been any {}
And then, it is perhaps good to sett a start value for ioc_status. My
suggestion is:
u16 ioc_status = MPI2_IOCSTATUS_OP_STATE_NOT_SUPPORTED;
Kind regards
