6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jakub Kicinski <kuba@xxxxxxxxxx>
[ Upstream commit f6c8f5e8694c7a78c94e408b628afa6255cc428a ]
When we set members of simple nested structures in requests
we need to set "presence" bits for all the nesting layers
below. This has nothing to do with the presence type of
the last layer.
Fixes: be5bea1cc0bf ("net: add basic C code generators for Netlink")
