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.
