We are evaluating modifying this to pool based OXIDs in the next version.

Thanks for the pointer, Hannes.
Sure. I'll include this change in the next version.

Sure. I'll do that. Thanks.

I had not thought about that. Thanks for pointing this out.
I'll make the change in the next version.

> Tsk. Fixup the patch introducing fnic_fdls.h instead.
fnic_fdls.h was introduced in patch 2. This is patch 6. The only concern with fixing up this
patch with fnic_fdls.h is that it will break compilation of the intermediate patches i.e., from
patch 3 to patch 5. I would like to avoid that.
However, what I can do is to move these function declarations to patch 2, if that would be
okay.
