No wifi with AC88 since 5.19.0-40: increase max_flowrings limit 256 to 512

[BiAiB]

Ubuntu can't see my wifi adapter since 5.19.0-40 kernel update (works wih 5.19.0-38)

The bug is described in this answer:
https://answers.launchpad.net/ubuntu/+question/706179

The cause is that a check has been introduced on max_flowrings > 256 (https://patchwork.kernel<email address hidden>/) being accounted for a faulty device behaviour when it's the default value for the asus AC88 wifi adapter.

Can the check be removed or the value increased so that I can use my wifi adapter ?

switching to "confirmed", since I can't run apport-collect without internet connection, obviously.
