Hi Markus,

This change seems reasonable to me.  However, I am assuming that as a
non-bug-fix, this is targeted at net-next.  And net-next is currently
closed for the v6.12 merge window.  Please consider reposting this patch
once net-next reopens.  That will occur after v6.12-rc1 has been released.
Which I expect to be about a week from now.

Also, for networking patches please tag non-bug fixes for
net-next (and bug fixes for net, being sure to include a Fixes tag).
