Sounds like a genuine net-next material. Please drop the Fixes tag
completely, and repost after net-next reopens
If someone disagrees please speak up.
## Form letter - net-next-closed
The merge window for Linux v7.4 has begun, and the net-next
tree is now closed for new drivers, features, code refactoring
and optimizations. We are currently accepting bug fixes only.
Please repost when net-next reopens. There is some uncertainty
about how long this merge window will last, so please check
https://netdev.bots.linux.dev/net-next.html
before reposting. net-next _may_ reopen on Nov 2nd.
