> Commit 3cbdb0343022 ("ice: Add support for E830 DDP package segment") incorrectly removed support for package download for packages without a signature segment. These packages include the signature buffer inline in the configurations buffers, and not in a signature segment.
>
> Fix package download by providing download support for both packages with (ice_download_pkg_with_sig_seg()) and without signature segment (ice_download_pkg_without_sig_seg()).
