A small status update: - https://github.com/fortra/impacket/pull/1714 has been merged, thus any patch related to this is now redundant. - https://github.com/fortra/impacket/pull/1715 has been redirected to https://github.com/fortra/impacket/pull/1721 which is pending approval.
As a result, once #1721 is merged, I'll be updating this ticket again to ask you to update the impacket's package instead of applying patches. Kind regards.
