I thought your comment was directed to Jabuk.

I don't see how to avoid that and at the same time changing
the type of the conflicting object and fix the warnings:

-			struct mlx5e_umr_wqe   umr_wqe;
+			struct mlx5e_umr_wqe_hdr umr_wqe;

My first patch avoids the need to introduce a bunch of `hdr.`
changes. However, `hdr` is introduced as an identifier for
the members grouped in the new type `struct mlx5e_umr_wqe_hdr`.

Of course struct_group_tagged() also creates an anonymous struct,
which is why we can avoid all those `hdr.` changes in v1.
