Hi Dave,

   I'd rather have this patch go through scsi-misc. Most, if not all,
libfc, libfcoe and fcoe patches have taken this path. The way it has
been working is that I have been collecting fcoe patches and re-posting
them to scsi-misc after I have reviewed them and done some basic
testing.

   Taking a patch like this through net{-next} could cause a merge
problem at Linus' level if a later patch makes it though the normal
process and conflicts. This is what I want to avoid.

   This patch, although appreciated, isn't critical. I have collected it
into my tree and will re-post it to scsi-misc. I see no reason to treat
this patch differently from other patches.

   Ultimately I just want things to go smoothly, so I'll leave it up to
James and you to figure out what to do.

Thanks, //Rob
